The suspected triggerman in a fatal shooting on Interstate Highway 80 that killed 20-year-old Richmond resident Kevin Santisteban on Sept. 5 has been arrested and charged, according to police.

On Thursday, Oct. 15, Tyejuan Shepherd, 18, of Richmond, was arrested by investigators in El Cerrito, police said. He was subsequently charged with murder with special circumstances by the District Attorney’s Office, police said.

The day after the shooting, on Sept. 6, police arrested two men in connection with the homicide — 21-year-old Jorge Vazquez and 23-year-old Camille McAlister, both from Fairfield. Police say public safety cameras in San Pablo and on the freeway helped identify them and they were subsequently charged with murder with special circumstances by prosecutors.

Believing a third suspect was present at the time of the shooting, San Pablo police continued their investigation, leading to the arrest of Shepherd.

“Shepherd is believed to have been the person responsible for actually firing the shots during the homicide,” police said in a statement.

Santisteban was reportedly traveling in a vehicle with two friends on I-80 near San Pablo Dam Road when he was struck by gunfire that came from a passing vehicle, according to police. An online fundraiser launched in the wake of his death raised over $30,000 to support his grieving family who lost their youngest son.
