A Contra Costa County Superior Court judge sentenced Concord resident Mark Navone to a 22-year prison sentence after he pled guilty to numerous counts of throwing objects at vehicles on Highway 4 – resulting in the death of one person and the blinding of another.

Navone was arrested after a California Highway Patrol (CHP) investigation identified him as the person responsible for throwing rocks and bricks at passing cars in a series of crimes that horrified local motorists in 2020-2021.

Investigators said Navone’s actions resulted in the death of a 63-year-old grandmother from Antioch and the blinding of a 37-year-old delivery nurse from Concord.

He was arrested on April 2, 2021, by Contra Costa Area CHP officers on a wide range of felony charges.


  1. Twenty-two years is an inadequate punishment for being the cause of such horrific tragedies.

    Fifty years to life seems more justifiable.

  2. If he behaves himself and doesn’t throw any bricks while in prison, he’ll get parole in about 11 years so he can resume his career.

  3. Makes you wonder about the thought process if any. You know, today I think I’ll go down to the freeway and throw rocks at passing cars. People who think like this should not be allowed to live with the rest of us. 22 years sounds like a good start.

  4. Time in state prison will not be nice but I can’t help but think of his victims and think it should be more…..

  5. Yeah he caused the death of one and the blinding of a health care worker he should get at least one life sentence.
