He was done taking crap from prosecutors. So a suspected California bank robber decided to dish out some of his own —and sickeningly ate a handful of his own feces while on the stand. Andrew Gilbertson said it was the Virgin Mary herself who suggested he make the disgustingly dirty protest at San Luis Obispo Superior Court on Wednesday, reports Cal Coast News. The 40-year-old convicted sex offender is on trial for allegedly robbing a Bank of America branch in San Luis Obispo in 2013. He allegedly wore a hat and a pink child's backpack for the raid, according to KSBY. Again, the Blessed Virgin is said to have spurred him on. The Paso Robles resident is pleading not guilty by reason of insanity. Chaos broke out in the court when Gilbertson took to the witness stand on Wednesday, the San Luis Obispo Tribune reported. He allegedly, under the instruction of the Holy Mother, reached into his pants and removed his own waste. Gilbertson is then said to have started chowing down on the impromptu snack. Judge Donald Umhofer ordered a recess. SAN LUIS OBISPO POLICE The convicted sex offender is on trial for allegedly robbing a Bank of America branch in San Luis Obispo in 2013, which he says was also influenced by the Virgin Mary.
