Three Sonoma County residents were in jail Monday night, suspected of kidnapping a Petaluma man at gunpoint from his Sixth Street home, police reported.

A call to police tipped them to the alleged crime and officers stopped a car not far from the home, reported Petaluma police Sgt. Marty Frye.

Inside they found the resident, three suspects, a loaded handgun and some methamphetamine, Frye reported.

Officers arrested Genoveva Ramirez, 28, of Santa Rosa, Eduardo Hernandez, 32, of Sebastopol and Raul Atilano-Lopez, 29, of Penngrove on suspicion of kidnapping and robbery, possession of methamphetamine for sale and other charges.

Police said the crime occurred just before 9 p.m.

The witness called 911 to say she'd seen a person taken at gunpoint from his home and put into a car. The description of the car helped police make the stop, officials said.

There were other family members with the victim at the house who were threatened with harm during the kidnapping, Frye said.

Officers booked the suspects into the Sonoma County Jail.

Officials asked anyone with information to call detectives at (707) 778-4372.
