The legal woes of the one-time Charlie Brown continue, as former child actor Peter Robbins pleaded guilty to making criminal threats Tuesday, the AP reports. The 59-year-old, who voiced the popular Peanuts character in multiple TV specials in the 1960s, has been charged with offering $50,000 to have the sheriff of San Diego County killed and threatening the manager of a mobile home park. Robbins blames his behavior on bipolar disorder and paranoid schizophrenia. "I want justice to be served, but I’m mentally ill," NBC San Diego quotes Robbins during the hearing Tuesday. "To stick me three years into a state prison is not benefitting the justice system. I feel I’m entitled to at least a second chance."
But depending on who you ask, Robbins may have already gotten that second chance. In 2013, he was arrested for stalking and threatening his ex-girlfriend and her plastic surgeon, NBC reports. Robbins was apparently upset about her boob job. He pleaded guilty to those charges and was sentenced to jail time. He was arrested again upon his release for allegedly violating his probation. He reportedly used some of his jail time to send threatening letters to the sheriff and mobile home park manager, who once testified against him. Robbins had been gaining a reputation for outrageous behavior in the courtroom, but he's gone on medication and was noticeably calmer Tuesday. The star of A Charlie Brown Christmas and It's the Great Pumpkin, Charlie Brown is facing more than four years in prison. (Read more Peter Robbins stories.)
