CHP: Concord Freeway Rock Thrower Arrested For Murder

April 7, 2021 20:14 pm · 45 comments

The man police say is responsible for throwing rocks off freeway overpasses in Concord, has been arrested, and he’s being charged with murder, according to the California Highway Patrol.

On April 2, 2021, at approximately 5:00 p.m., Contra Costa CHP Officers arrested 46-year-old Concord resident Mark Lawrence Navone in connection with numerous brick and rock throwing incidents onto the freeway that occurred in the area of State Route-242 and Highway-4 over the past year.

Navone’s actions resulted in the death of a 63-year-old grandmother from Antioch on April 10, 2020, according to the CHP. Additionally, his actions maliciously deprived a 37-year-old delivery nurse of Concord of her vision.

He is currently being held without bail at the Martinez Correctional Facility.

The Contra Costa County District Attorney’s Office is filing the following felony charges against Navone;

  • 1 count of Murder
  • 5 counts of Assault with a Deadly Weapon
  • 1 count of Mayhem

Throughout this investigation, there were approximately 40 incidents reported of rocks or bricks being thrown at cars in the described area between September 2019 and January 2021. Through surveillance, DNA, evidence, witness statements, and many hours of investigation, CHP investigators identified Navone as the primary suspect in these incidents.

Good job CHP

They had to take him alive?
That’s a pity….. too bad./

The caught him, if he is the right guy he will stand trial, and be convicted and punished, and hopefully be put away for the rest of his life. That is our system, and although tempting to wish for something more heinous, I think following the system serves us best.

If we could only count on that happening Hanne. Unfortunately, that’s not how it typically works anymore in California. If he is convicted of all charges (and that’s a big if), he’ll probably only serve 7-10 years.

#hanne: I always enjoy reading your posts no matter what the issue. You give a wonderful insight with your European twist on it. ( I came from Europe too)
And your advice on this one sounds reasonable too. However I’m going to be very skeptical. Our American judicial system is broken. I see this man is being turned loose and throwing rocks once again off the freeway probably within a few months. No matter what the laws say, the crazy liberal progressives have immense pity and compassion on him and none for the rest of us good innocent citizens who pay all the taxes and obey all the laws. They seem to disdain us in favor of supporting the freedom of the freaks. I’m not sorry to say that. We have been things so upside down and out of perspective it has gotten ridiculous. All of society is suffering as we cater to the special groups.

Well done! Hope they got the right guy.

Death by stoning might be appropriate if convicted.

qwerty April 7, 2021 at 8:46 PM

Thank God. Thank you to the police for catching the murderer. This is the best news I’ve read all year.

Mom April 7, 2021 at 9:02 PM

I agree! Best news all year! I’ve been worried about this.

Led April 7, 2021 at 9:10 PM

Very glad they found him. He could easily have killed or maimed even more people, given how many incidents there were. Horrible.

This must have been a huge investigative effort – I’m so glad they got this fellow. What a wicked man!

Amy April 7, 2021 at 9:46 PM

I hope he goes to prison.

Mom April 7, 2021 at 10:13 PM

He better go to prison if he’s guilty and kept there but who knows in this crazy state. I really appreciate CHP’s work on this. I’m so curious to know more about the case.

Wayne Calhoon April 7, 2021 at 11:06 PM

There is a copycat out there, or he hit my windshield from the Olivera/242 overpass a week before his arrest.
Scared the poop out of me.
Glad dude is in cuffs.

Robert April 8, 2021 at 8:43 PM

Did you report the incident to the CHP? Of course it may not have been him because generally he throws bricks and you would’ve had a lot of damage if that had happened. Or worse! Thank goodness it wasn’t more serious!

Googlar April 8, 2021 at 1:33 AM

Prison is a waste of taxpayer money. They should hang this coward from the overpass.

Kauai Mike April 8, 2021 at 4:59 AM

BRAVO CPD!!!! Thank you!

Blood is on liberals’ hands – keep dismantling society – one day it will be you or someone you love.

Look at it April 8, 2021 at 10:06 AM

Exactly! Democrats have so much blood on their hands.
I’m happy this guy was arrested, but in Commiefornia he may not stay in prison where he should spend the rest of his life!

Leoclown April 8, 2021 at 10:46 PM

Who said anything about CPD? In such a hurry to comment you fail to read…

KingOfC April 8, 2021 at 6:03 AM

Nice!, hopefully he shows up to his arraignment in a wheelchair from getting beat up in County!

Chester April 8, 2021 at 6:51 AM

Great job, CHP!

Janon April 8, 2021 at 7:08 AM

THIS OVERPASS NEEDS 24/7 SECURITY!!!!! One death and several injuries is TOO MANY!!!!!

Randy April 8, 2021 at 7:27 AM

.lock ’em up – throw away the key… unfortunately in Cali they’ll let him go in a few years

remember April 8, 2021 at 7:31 AM

Thank you CHP!!

May God bless you all

Rolaids April 8, 2021 at 7:35 AM

Thank God! Praise be unto the CHP, and any other police involved in this investigation. I’ve heard a lot of talk on the interwebs lately about how police don’t prevent crime, they just show up afterwards. This was a crime that needed to be prevented, and hopefully they got their man. Thank you thank you thank you to our men and women in blue. Or khaki!

Jeff April 8, 2021 at 7:56 AM

Nice work CHP and CPD. 108RS

sam malone April 8, 2021 at 8:01 AM

Now can we start to pursue the others who set fire and destroy our city and state and fully prosecute them-hear us DA’s-loud and clear.

The Wizard April 8, 2021 at 8:02 AM

Drop him off with a noose around his neck at the same overpass he killed that women.

JR April 8, 2021 at 8:17 AM

Great News!! I wish we could put cyclone fencing around ALL overpasses.

Local Lady April 8, 2021 at 9:03 AM

Still wondering, why?

FPN April 8, 2021 at 9:54 AM

Thank you for catching this criminal. Records state he is a electrician and lives on Monument. Graduated from Ygnacio Valley High so he is a local boy.

Ricardoh April 8, 2021 at 10:07 AM

What would inspire a person to commit such a crime. I can see a stupid kid who is a little whacked do that but not an adult. So diminished capacity or not he has to be locked up forever.

Noj April 8, 2021 at 11:22 AM

This dirtbag has been in trouble for years. A felon with priors. That’s why. He lives in a trailer park off of Monument Bd.

From…June 2009

Mark Lawrence Navone; S.P.D.’S “Most Wanted”Sonora, CA — 34 year old Mark Lawrence Navone is this week’s “Most Wanted” by the Sonora Police Department.

Navone is six feet one inches tall and weighs 180 pounds. He has blond hair and blue eyes.

Navone has a felony warrant for being a felon in possession of a firearm and shooting from a vehicle.

Ricardoh April 8, 2021 at 1:14 PM

A real loser. I think he can kiss away the trailer park for good.

tashaj April 8, 2021 at 10:12 AM

East Bay Times had a bit more on this. It turns out, that the guy was first arrested 2 weeks prior, when he was walking down SR242 with a backpack full of stones and bricks. And he was let go. Then they’ve rearrested him. In the meantime there was at least one more incident – remember that report of a log thrown into traffic? Luckily nobody was hurt.

Also as the attacks continued and since they were happening late in the evening with few witnesses around, CHP tried to run a surveillance op on SR242 by placing an unmarked car on the shoulder with a camera inside. The only result was a catalytic converter stolen from this unmarked car.

The guy has quite a bit of criminal history and the most likely reason for doing all this is just that he’s a nasty piece of $hit. Yes, unfortunately, some people are like that.

Antler April 8, 2021 at 10:27 AM

And I’ll go further to add that it is ludicrous to spend millions of dollars to hang cable netting from the sides of the Golden Gate Bridge to stop people who WANT to kill themselves (and probably for valid reasons)…… but then to leave commuters, vacationers, truckers, and local area residents completely at the mercy of anyone who decides to chuck things down from overpasses onto drivers.

Sending thanks and respect to all the different staff personnel, investigators, and officers who effected this arrest ….. and to all the K-9 officers who wished they could have been in on it!

Old Concordite April 8, 2021 at 11:44 AM

So you are thanking the Office of the District Attorney as they would also be involved in the investigation with their own Investigative Unit
Inspectors and non sworn staff.

Pinata Justice April 8, 2021 at 10:29 AM

Hang him by his foot from that overpass and let traffic provide justice.

JimmyJam April 8, 2021 at 11:54 AM

Probably marked that death as Covid-related right @parent?

Mitch April 8, 2021 at 12:46 PM

What an absolute dreg of society.

Would be nice if they would use this idiot as an example, then clean out the homeless encampments that litter every underpass, entrance ramp, and even on the side of the freeway.

People and roads do not mix. Yesterday in Pleasant Hill, there was shantytown set up on the shoulder in a very narrow spot, next to a fence and barrier. Imagine setting up in a 3 foot wide section directly next to the freeway.

County Supervisors, where the hell are you at?

Who will volunteer to throw the switch on this poor misunderstood pos?

Chris April 9, 2021 at 10:25 AM

I wouldn’t have a problem with taking him up in a helicopter to about 5,000 feet and throwing him out into a shark infested ocean, but our D.A. probably has already decided he should pay for his crimes via several years of probation.
