Petaluma Police Descend On Home, Arrest 1 On Firearm Charges

PETALUMA, CA — A Petaluma man was arrested when detectives and SWAT officers descended to serve a search warrant Friday morning at a residence in the 500 block of Albert Way. Detectives were acting on information that a resident of the home, Christopher M. Rosen, 36, was possibly in possession of an illegal assault rifle and was suspected of trying to sell firearms via a website, police Lt. Tim Lyons said.

During the service of the warrant at 8:30 a.m. Friday, police detained Rosen and three other people while a search of the residence was conducted. The search turned up an assault rifle determined to be stolen out of a residential burglary in Cloverdale, Lyons said.

Also recovered were two other firearms and over three pounds of marijuana being prepared to be shipped out of state, the lieutenant alleged.

As a result of Friday's search, Rosen was arrested and booked into Sonoma County Jail on suspicion of possession of firearms and having a criminal active protective order, offering to sell high-capacity gun magazines, offering to sell an assault rifle and possession of stolen property.

"All of the firearms were loaded and openly displayed in the [Rosen's] bedroom," Lyons said.

The other three people were released from custody.

Lyons added that in August, Petaluma police responded to reports of a robbery and shooting at the same house.

"It was reported that four black males robbed and shot at the subjects associated with the house," Lyons said, noting that the incident remains under investigation with no arrests yet made in the case.

Anyone with information pertinent to the investigation is asked to contact Petaluma police detectives by calling 707-778-4372.
