A report of a suspicious vehicle on Saturday led Dixon police to 31 bikes worth an estimated total of $15,000 that they suspect were stolen.

Police responded to a report of a van that was driving slowly around the parking lot of Walmart on Dorset Drive at 9:26 p.m.

People in the van were reportedly looking into vehicles in the parking lot, said Sgt. Glenn Cooper.

Police contacted Richard Hand, 39, and Kathryn Mceachern, 30, both of Davis, in a white Chevy “box van,” Cooper said.

Police discovered that Mceachern was on probation and searched the vehicle, he said.

Officers uncovered 31 bikes in the van ranging from $200 to $2,000 each, he said.

Further investigation revealed one bike had been reported stolen to the Davis Police Department and one was reported to San Francisco Police Department, he said. Two others were just confirmed stolen from the University of California, Davis campus, he added.

Mceachern and Hand were both found with methamphetamine and drug paraphernalia, he said.

They were arrested on charges of possession of stolen property, possession of a controlled substance, possession of drug paraphernalia and conspiracy, according to the Dixon Police Department.

Mceachern also was arrested on a charge of violating probation.
