Man Charged With Murder, Maimings After Brick, Concrete Assaults On Highway 242 Motorists

A suspect in a series of devastating roadside attacks on motorists traveling Highway 242 last year is in custody and facing multiple charges in connection with the assaults.

Investigators say Mark Navone, 46, who authorities said has been residing in Concord, is the man who hurled bricks and concrete at cars at passing autos – killing one woman and maiming another as the debris plunged through windshields and car windows.

The 2020 attacks spawned widespread regional attention and an extensive investigation. It was not immediately known what brought Navone to the attention of authorities, though several agencies reported involvement in his apprehension.

He is being held without bail for the April 10 death of Margarita Ruiz, killed by a brick that hurtled into her car, another assault in October and still another on Dec. 23 – which disfigured a nurse on her way to work in Concord when her car was struck by a rock.

Navone faces charges including murder, mayhem and five counts of assault with a deadly weapon in connection with the attacks.
