Surveillance video from September 6 shows him breaking into Bills Market on Highway 116 in Graton. Detectives say the man first disabled the alarm, then once inside, he used a power tool to cut into a box below the register.
He's described as a black man in his 30s or 40s, about six feet tall, wearing a white baseball cap, dark grey sweatshirt, and blue jeans.
The same man is suspected in at least two other commercial burglaries in northern Sonoma County.
