A man suspected of breaking into several post office boxes in Sierraville was arrested for allegedly having 3 pounds of hallucinogenic mushrooms.

On Sept. 10, Sierra County Sheriff John Evans responded to the reported break-in and theft of mail from post office boxes in Sierraville.

The thefts seemed to be random, the Sierra County Sheriff's Office said.

Evans found a man in Cold Creek Campground about five miles south of Sierraville, who matched witness descriptions of a suspicious man they had seen in the area of the post office who was said to be heading southbound towards Truckee.

Evans found the man had more than 3 pounds of dried psilocybin mushrooms.

Robert Lyle Bennett, 57, of Bisbee, Ariz., was arrested for possession of the mushrooms.

It is believed to be the largest amount of hallucinogenic mushrooms seized by law enforcement in California this year, according to the Sheriff's Office.

A sample of the mushrooms has been sent to the California Department of Justice laboratory for complete analysis.

The investigation of the break-ins and thefts of the post office boxes is being investigated by two inspectors with the United States Postal Service. Investigators believe that the motive for that crime was personal gain through forging checks or obtaining personal information for identity theft.
