A Santa Rosa man suspected of drinking in public and resisting arrest was in custody and had been searched when Sonoma County sheriff’s deputies found he’d also been carrying a loaded handgun, a sheriff’s official said Monday.

The handgun was spotted on the floor of a deputy’s patrol car after deputies had Guadalupe Velasquez, 24, handcuffed and his legs bound late Saturday night, said sheriff’s Sgt. Spencer Crum.

Crum said Velasquez wore several layers of thick clothing. A search of Velasquez before being placed in the patrol car turned up several 9‑mm handgun rounds in a pocket, Crum said.

The loaded, 9-mm Smith & Wesson, which deputies suspect Velasquez dropped to the floor, had been stolen in Contra Costa County, Crum said.

Velasquez was arrested on suspicion of having a loaded, stolen gun in public, obstructing a deputy with violence and violating his probation for a DUI conviction. He was released after posting $36,000 bail.
