UPDATE: Suspect in Fatal Concord Hit & Run Crash Arrested by CHP for Alleged DUI an Hour After Crash

March 18, 2014 10:57 am · 70 comments


A 29-year-old man who allegedly fled from a crash that killed a homeless woman in Concord late Sunday night was arrested on suspicion of drunken driving early the next morning, a California Highway Patrol spokesman said.

Police said officers arrested Tyler Neal Larson of Antioch on Monday on suspicion of felony hit-and-run.

Investigators believe he fled the scene after his truck left the roadway and fatally struck 46-year-old Yolanda Tiscareno as she was walking around 11:40 p.m. on a sidewalk on Willow Pass Road near Fifth Street, according to police.

Emergency responders pronounced her dead at the scene.

A little more than an hour later, CHP officers in the area stopped Larson in his 1997 Chevrolet Silverado pickup truck on suspicion of DUI, according to CHP Officer John Fransen.

Fransen said the officers later saw that Larson’s truck matched the suspect vehicle description in an alert to law enforcement about the fatal hit-and-run collision and immediately informed Concord Police, who arrested the suspect on Monday afternoon.

He was taken to county jail in Martinez where he is being held in lieu of $100,000 bail.

Fantastic work getting this killer where he belongs to all involved! Hope he can stay locked up a really Loooooooong time! I do feel safer.

Dude needs a serious lawyer!! Why do E. CoCoCountians always do all their law breaking and mayhem on this side of the hill??

JET March 18, 2014 at 11:17 AM

$100,000 bail? THATS ALL? Well, this guy will be out by the end of the day….. unbelievable.

Enfield303 March 18, 2014 at 11:18 AM

Sooooo… he was pulled over by CHP for suspicion of DUI and let go?

CLAYCORD.com March 18, 2014 at 11:24 AM

Enfield303, the story says he was arrested. Usually what happens is they arrest him, then find the person a ride home and let them go. At that time, they had no clue he was also wanted for the hit & run crash in Concord.

LilRedHead March 18, 2014 at 11:23 AM

Wow thats great news but a bit confussed. It said he was arrested early monday morning for dui. But later in the day Monday they got the info and went to his house where he & his truck were and arrested again for the hit and run. Thought when you got a dui they arrested you and impounded the vehical. Guess im confused still. Bottom line happy they caught him

Enfield303 March 18, 2014 at 11:28 AM

Thanks for clearing that up Mayor. Someone explained it in another thread.

Michelle March 18, 2014 at 11:28 AM

Why do we have the nut cases come over here!

Huh? March 18, 2014 at 11:34 AM

So if you get arrested for DUI you don’t get booked in county, but instead they call you a friend to pick you up? Is that part if the new jail laws or something? How absurd. So essentially they are not cleaning up the streets and letting drunks go and possibly finding another vehicle to get into, drive and possibly kill another person while fleeing the scene? WOW, I’m speechless!!!!

Guy from West Pittsburg, CA March 18, 2014 at 11:42 AM

Can the lady he killed be the homeless lady i bout water for when i seen her digging in trash cans for cans and bottles? Who said young adults from West Pittsburg dont have hearts that care for other?

Scott March 18, 2014 at 11:45 AM

Our prayers go out to the family and friends of Yolanda. So sad.

Edith Bunker March 18, 2014 at 11:49 AM

So many people on drugs on the road and the car next to you is probably stolen and carrying guns.
Drive defensively

Landana March 18, 2014 at 11:52 AM

Wow, I wonder how drunk he was. How do you kill someone , get pulled over an hour later and hold it together. Not saying his story would be true, but i’m curious to hear why he flead and never confessed when he was pulled over.

Sofaking March 18, 2014 at 12:13 PM

The truck reported to CPD was a white silverado even though he had a black one. Thanks to whoever the sh*tyy witness was, I was pulled over at around a little after midnight and questioned for almost an hour which led to me being sleep deprived for a very important day. CPD accused me of the crime right from the start! No longer a fan of the police department, they need to relearn innocent until proven guilty.

With a DUI March 18, 2014 at 12:27 PM

and perhaps the felony manslaughter hit and run, leaving the scene of an accident and being an ugly creep, how long could this clown be sentenced to jail. 6 years tops? And then perhaps released early because he does not meet the criteria of being a threat to society? (I know he can’t be sentenced for being a ugly creep but he is guilty of being that)

Anon777 March 18, 2014 at 12:28 PM

KARMA got his A$$ quick!

Mustang Sally March 18, 2014 at 12:34 PM

I swear it looks like Ted Neugent planted a wayward seed with this guy’s mama.

j March 18, 2014 at 12:38 PM

@Sofaking you deadbeat. You should be locked up with him. A woman died in cold blood. If you had an important day what the hell were you cruising for after midnight. Kudos to the PD for doing a secure sweep. Hats off to them.

Puddintain March 18, 2014 at 12:39 PM

@Rick, you’ld know, woudn’tcha?

Theresa Tiscareno Soares March 18, 2014 at 12:53 PM

$100k bail? He is going to be out in no time. He killed Yolanda and they are
going to release him so he can get drunk again and kill someone else.

The Southern Cross March 18, 2014 at 12:54 PM

Mrs Tiscareno was apparently homeless and sleeping in the streets. Yet she has four children in the area who knowingly let their mother be a vagrant? What he hell is wrong with her kids?

This dirtbag Larson must be of the same mentality.

ProfessorGas March 18, 2014 at 12:55 PM

They book DUI’s and often take them home. I had a roommate go through that the CHP only allowed her to stay home provided I promised I would not let her drive. Stop freaking out, people.

Landana March 18, 2014 at 1:05 PM

At least they now have proof that he was driving under the influence, and they were able to catch him because of it.

@Southern Cross March 18, 2014 at 1:17 PM

I was thinking the exact same thing. Poor woman would not have been on the streets is someone had given a dang.

Landana March 18, 2014 at 1:17 PM

Such a bold statement, you must know the family. You also sound very ignorant in your understanding of the homeless.

Instagramma March 18, 2014 at 1:34 PM

insensitive or ignorant? Probably both

Sunnymoon March 18, 2014 at 1:35 PM

I can’t believe he was STILL driving an hour after the crash. Usually people go into hiding after a hit and run. This one was joy riding.

Rebecca March 18, 2014 at 1:53 PM

I’m 46 and my oldest child is only 14. Please don’t start blaming her children for not taking care of her. I don’t know how old her children are but now is not the time to blame them for not taking care of her.

Cite releasing DUIs March 18, 2014 at 2:18 PM

DUIs are usually arrested , tested and a ride is arranged for them. This puts the Officer out on the road sooner, much sooner.In the case of the CHP with 5 units on graveyard, tying an Officer up babysitting a DUI to jail and filling out all the booking forms can easily mean no CHP Officer available. for wrecks or to catch other DUIs. Cite release was instituted about 20 years ago, and its a good policy
Of course a DUI who resists, runs his mouth off too much or acts like a jerk gets a trip to County jail. They subsequently cite and release them.

Koko March 18, 2014 at 2:22 PM

How can you be DRUNK DRIVING, get pulled over and let go with a slap on the hand? I know CHP didnt know he was the one involved in the fatal incident. But, Didn’t they know there was a fatal accident in concord where he might have been the aggressor?! With the same characteristics mentioned?! And still let him go?!!! WHAT THE HELL!!!!!??? (To put it in a not offensive way) really!!! What if the person driving was of a different race? I’m sure this would have turned out diferently….hmmm

Good neighbor March 18, 2014 at 2:23 PM

@southern cross
You don’t know anything about the local homeless I guess! You cannot force a 46 yr old woman to live a normal life no matter how much you may want to. MANY of our local homeless have the option if living with family but they do not want to! I have a relative who may as well be Yolanda. She comes and goes, shows up to eat, shower and sleep in a clean bed for a few days and then off she goes. She has adult children as well

Well Informed Citizen March 18, 2014 at 3:03 PM


He was stopped by the CHP an hour after the fatal collision. He was ARRESTED by CHP for DUI and BOOKED at the county jail and CHP did TOW his truck. They knew his truck was damaged but there was no evidence/info to them at the time he actually ran over someone. He was released that morning from jail and went to the tow yard to pick up his truck. The CHP officers saw the news the next day of where the collision happened and called Concord PD with the lead. A few hours later, Larson was arrested again at his house.

His booking info and all is public info and this was vague with the media but a little digging sure cleared this up.

Congratulations KoKo you made the biggest idiot list today, edging out Sofaking , but not by much.

I know Tyler, he was our neighbor since I was a baby.. Him and his sister are nothing but dirt bags…

Sue -em March 18, 2014 at 4:35 PM

I checked out “DudeMan Calhoun” on facebook. This is the alleged suspect. He clearly sends a picture post at 10:28 PM Sunday Night. Approx a little over an hour before he found his way onto Willow Pass and stuck and killed a person walking. What bar is he leaving? We all know that this place will have ramifications for allowing such a drunk person to leave their establishment. I’m not blaming the place for his inebriation – however, there are laws that clearly put some liability onto the serving establishment.

Spanky Fortuna March 18, 2014 at 4:45 PM

@ Rebecca March 18, 2014 at 4:57 PM

Well let’s just say the family members will always live with the fact their homeless relative was killed on the streets, when she should have been in a warm bed., or even on the floor at their living quarters.
I would never have let my Mother walk the streets at night with a shopping cart. EVER! Would you?

Royally Pissed Off March 18, 2014 at 5:24 PM

@ Southern Cross. You sure are quick to judge a family who has gone through nothing but tragedy after tragedy. You do not even know the story behind this all and are being completely ignorant to the ENTIRE Situation. A family just lost their mother. have some decent courtesy for god’s sake….judging by your name, I thought you would know that being a christian meant that you should never judge anyone. These children have poured their hearts out to their mother, tried to give her shelter, assist her with her DISABILITY, yet she refused their help. You can’t change an adult’s mind when they are set in there ways and do what is comfortable for them. What kills me is these kids are going to read your comment and even feel worse about their mother’s tragic death that shouldn’t have even happened. And sure the news says “grown children”, but these kid’s are in COLLEGE. How do you expect these kids to take take care of their mother who didn’t want any of their help. I guess you’d just like to see four more kids on the street then, rather than getting an education and succeeding in life. That’s my two cents on it. I think you owe this grieving family an apology.

Landana March 18, 2014 at 5:24 PM

By law you can not force them if they don’t want too. Many of these people have family members who want them home, who check on them and do the best they can to make sure they are alright.

I guess there are a lot of people out there who think the homeless are people who just lost their job or can’t find one, there familys just all say oh well.
The people who think like this are unwilling to help them, I know this because they would not be saying these things if they ever spent time with them.

RIP Yolanda March 18, 2014 at 6:00 PM

@thesoutherncross I agree with RoyallyPissedOff.
Ignorant indeed. It is ashame that you are quick to judge and blame her children who not only did everything they could to help her get off the streets, they spent a lot of their energy and love to revive a relationship they wanted. She was an innocent pedestrian just walking with a friend. Would you blame a husband or wife for their partner walking home from work or running an errand? Would you blame a parent if their kid was simply walking home from school? This could have happened to anyone and anytime. Yet you blame her grieving kids?

@Landana March 18, 2014 at 6:26 PM

Then perhaps they could have gotten her psychologicaL help with her issues of choosing to live on the dangerous streets. Very odd indeed!

94519 March 18, 2014 at 6:34 PM

Now that the facts are out, the speculators ,
and pre-mature judges should rethink their
posts and hold on until the truth is known,
regarding the actions of the C.H.P..
And the ignorant views towards people that
suffer with mental illness, including their family
members. should just be ashamed.

Noflow March 18, 2014 at 6:57 PM


I bet he is a pothead!

@94519 March 18, 2014 at 6:58 PM

No fact would change minds about that woman walking the streets at night to her death.
The family should be ashamed.

Fig Newton March 18, 2014 at 7:54 PM

Super Tweek,,,,,,,,,,,,,, a real loser,,,,,,,,,,,,, I hope he has a Extended stay in gray bar hotel!

Landana March 18, 2014 at 8:08 PM

You can’t make someone get psychologicaL help, people that are mentally ill don’t want that kind of help. Maybe you’re too young but, Reagan changed that law regarding mental ill people, family no longer has the right to force someone to get help against their will. Its becoming very obvious that you are a troll.

Southern Cross is a Fricken idiot March 18, 2014 at 9:31 PM

How dare you Southern Cross and Rebecca. You both are idiots and somehow must know the Tyler. Blaming the family members that Tyler left Vinnies drunk and went out and killed someone.. These kids and her siblings tried consistently to get her off the streets. You cant force someone to do what they don’t want. I’m praying that karma comes back to both of you.

concord March 18, 2014 at 10:05 PM

It is so dark over there, I’m surprised another person was hit. This is the second person hit in that area late at night in a couple of months. I know if I’m getting off of work and leaving Concord BART at that hour, it is easy to not see someone. That guy doesn’t look like a pot head or a drunk; just a douche who panicked and left the scene of an accident that she should not of and he will pay dearly for that. Vinnie’s on the other hand are a bit irresponsible in cutting people off but hey CPD could be on that and they aren’t.

concord March 18, 2014 at 10:06 PM

I should have said I’m NOT surprised another person was hit.”

concord March 18, 2014 at 10:08 PM

Wonder if she is related to Anthony Tiscareno, Antioch City Council Member?

Maynard G. Krebbs March 18, 2014 at 10:44 PM

Vinnie’s is not responsible for the drugs he took…j Sounds llike he was hallucinating and on a binge…He ain’t no Dobie Gillis!

Anonymous March 18, 2014 at 10:51 PM

Good Lord “Concord” She was walking on the sidewalk! wasn’t on the street or a crosswalk. Talk about blaming anybody but the drunk..

I love the people who criticize the victims family without knowing squat, or blame CHP for not knowing about the wreck, or blame Concord PD for stopping them. And the list goes on.

Bottom line: drunk killed an innocent person. Pretty close to murder if you ask me.

@ Southern Cross is a Fricking Idiot March 18, 2014 at 11:06 PM

This is Rebecca and my original post #29 was defending her children in response to The Southern Cross’ post #22. I believe your negative comment you directed toward me was actually in response to the post #39 which was also (I think) from Southern Cross attacking me for defending her children.

This is why I try not to post on here too often. People just don’t read before they post. I have the utmost sympathy for her family.

Anonymous March 19, 2014 at 8:00 AM

Rick March 19, 2014 at 9:52 AM


Nice grammar.

homeless victim March 19, 2014 at 11:05 AM

The media reported this thing with a definite slant. They said that the victim was a “mother who lived in the area.” What they could have said was that she was a mentally ill woman who was homeless, sleeping rough, pushing a shopping cart close to midnight at the time of her death. She was the mother of grown children. When you live on the streets bad things happen.

Concord has so many homeless, this isn’t the first who has been killed by a vehicle. One of the “Claycord 13” was run down on Clayton Rd. not long ago.

In this case, I blame the driver, I blame Vinnies if that’s where he got so drunk, I blame Yolanda’s children for letting her live the way she did, I blame the Concord City Council for failing to manage the homeless — for instance, camping in is a crime, and the violators can be taken to jail — which would get them off the streets. Being drunk in public is illegal too but you’d never know by the falling down drunks I’ve seen downtown near the plaza.

I blame the police and the police chief who don’t want to do their jobs because it is too much a nuisance to arrest and release and arrest again. So what? I pick up litter on my property constantly. Should I stop doing it because it is too much of a nuisance? At least these people are off the streets for a time if the cops actually arrest and incarcerate instead of issue a warning or a citation and leave them standing where they find them.

Standing in a median and begging for money is illegal, but I see a woman doing it almost every time I get off work.

I blame homeless enablers who draw crazies into the area with free hot meals, showers, laundry and mail service and haircuts, but then shut the doors in their faces when they close for the day — dumping their clients into the neighborhood. These charities contribute to the plight of the people they purport to help. They might as well give heroin to an addict.

Lest you think I’m a hard hearted jerk, I’m all for taking care of crazy people at taxpayer expense. They should live in shelters where they get meals and clothing, social services and medical care. If they are a danger to themselves or others, they should be in a locked shelter. Likewise there should be no other place where the homeless should be assisted, making it as difficult to live on the street as possible.

If you feed them, they will come.

Look what’s happening in San Jose, they’ve got 200 people living in absolute squalor in an homeless encampment. Probably rat and disease infested. Do they shut down the area? No, homeless outreach charities ask for volunteers to help clean it up a bit — picking up garbage and making things tidy. So now we provide the homeless with free housekeeping services. Ridiculous.

@ Southern Cross is a Fricking Idiot March 19, 2014 at 11:17 AM

#49, ” I’m praying that karma comes back to both of you.”

Wow. What a hateful person you are!! You’ll actually PRAY for someone to be hurt for just commenting on Claycord?? Are you really any better than the person/s who posted here?? Whether or not you agree with them it is pretty pathetic that you wish bad karma on another…….If they were mass murderers, THEN I could see praying for their demise……

@No name, please March 19, 2014 at 1:42 PM

That was an excellent, highly informative post. It’s a shame that most here probably won’t take the time to read it. Thank you for trying, anyway.

Cowellian March 19, 2014 at 2:02 PM

Y’all remember One flew over the Cuckoo’s Nest, don’t you? That was probably the tipping point that convinced society that individuals had a right to be crazy and forcing them into treatment was a violation of their civil rights. There is no doubt that some people with mental issues were abused by involuntary treatment, but you’d have a hard time convincing me that most street people are better off on the streets than in involuntary treatment.

The poor lady who was killed. I hope this young man will see how he is living a reckless life. I hope he is sorry for his driving drunk and killing a person. If not, I hope our justice system will let him know that he cannot do this anymore. I pray for the people hurt by his actions most of all.

It's the money March 20, 2014 at 7:57 AM

People think that crazies can’t be locked up because of their civil rights, but the face of California changed when Ronald Reagan shut down mental health hospitals for economic reasons, not civil rights.

A one time, long term neighbor March 21, 2014 at 8:38 AM

Tyler and his family were my neighbors for over twenty years. I watched him and his sister grow up. In the past he has had issues with his temper and hung around a group of very sketchy friends. His whole family has got issues. Knowing what I know about him, it doesn’t surprise me one bit that he made some very poor judgement calls that night. I feel sorry for the victims family. She was on the sidewalk, regardless of why, sidewalks are supposed to be safe for pedestrians- at any time of day. I hope they throw the book at Tyler for what he did.
