A Vallejo man is a suspect in a chase that injured a Petaluma officer

A Vallejo man is suspected of leading authorities on a chase that led to a collision with a Petaluma police officer in September, officials said this weekend.

Jason Gellman, 51, is being held in the San Mateo County Jail after being arrested earlier in an unrelated case, the Sonoma County Sheriff’s Office said Friday.

In Sonoma County, Hellman is charged with possession of a stolen vehicle and other charges related to the pursuit, officials said.

Sonoma County investigators said they have identified Hellman as the suspect in the Sept. 7 chase and crash along southbound Highway 101 near Cotati.

He is accused of driving off after a deputy tried to stop him for a traffic violation. Sheriff’s officials said he then drove recklessly, going over 100 miles per hour and driving on the wrong side of the freeway.

According to the sheriff’s office, deputies stopped the chase before Hellman “intentionally” rammed a Petaluma police officer’s car, causing minor injuries to the officer.

Hellman’s car was found abandoned, officials said, adding that they learned it had been stolen out of Solano County.

On Oct. 24, they searched Hellman Vallejo’s home in the 1000 block of Alabama Street.

Inside were several boxes of ammunition and Vallejo resident Adam Jackson, 42, who had a warrant for his arrest for violating the terms of his post-release community supervision in Napa County, they said.

Jackson is being held in the Solano County Jail on suspicion of being prohibited from possessing ammunition and on a warrant.

Investigators also found possible methamphetamine, which remains under investigation.
