Officers responded to a reported robbery at the grocery store at 621 E. Washington St., where a suspect had entered the store undetected before it was open to the public at around 6 a.m., according to Petaluma police.
The suspect, 20-year-old Rohnert Park resident Matthew Cryer, was allegedly able to gain access to the store's main office by cutting a hole in sheetrock and using a small crawl space above the office. An unsuccessful attempt was made to get into the store safe, but Cryer allegedly stole other items from the room and fled.
Police investigators located Cryer's vehicle in Rohnert Park and served a search warrant for his vehicle and home. Stolen property from the store was found as well as clothing worn during the burglary.
Cryer allegedly confessed to the crime after he was arrested for burglary and committing a felony while on bail.
He was booked at Sonoma County jail with bail set at $20,000.
