Jonathan Hoppner, 23, was booked into the Sonoma County Jail on Wednesday after a parole agent called police at about 4:50 p.m. from a Santa Rosa Avenue hotel where he had been staying, Santa Rosa police said. 
Hoppner, who has been convicted seven times for sexual battery during a three-year period, had apparently become upset during a visit with two state caseworkers, Sgt. Chad Heiser said. Hoppner physically intervened when they tried to leave, grabbing one of the caseworkers and punching him, according to police. 
The caseworkers called Hoppner’s parole agent and the agent alerted police. 
Officers arrested Hoppner on suspicion of felony false imprisonment, misdemeanor battery and violating parole. Hoppner was being held without bail Thursday at the jail and was scheduled for a court appearance at 1:30 p.m. Friday.

State parole officials said they were aware of Hoppner’s arrest and that his parole status is on hold while the current case is handled in Sonoma County Superior Court. 
The arrest came nearly a month after Hoppner’s release from jail for a 2015 conviction. His release led two Sonoma County police agencies to issue a series of public warnings that he was checking into local hotels. Those warnings caused Hoppner to get kicked out, first in Petaluma and then in Rohnert Park.
According to public court records from Hoppner’s previous criminal cases, Hoppner is developmentally disabled and has undergone competency reviews by doctors. 
Sonoma County Public Defender Kathleen Pozzi said that registered sex offenders have limited options for where they can live. Additionally, most residential programs serving developmentally disabled adults are barred from accepting registered sex offenders, Pozzi said. 
“He does need to be in a facility and the question is, what kind of facility is that?” said Pozzi, who noted Hoppner’s seven criminal convictions for similar offenses. “Is it a prison or a hospital?”
Hoppner has been convicted for crimes that follow a consistent pattern of assaulting women in public places, grabbing buttocks and breasts and hitting them, often during daylight hours. His victims have ranged in age from 15 to 50.
Hoppner’s most recent conviction stemmed from a July 2015 incident in which he grabbed a 15-year-old girl, groping her buttocks, at Santa Rosa Junior College, despite a judge’s order that he keep away from campus because of a prior assault there in 2013. 
Hoppner was given a 18-month sentence for misdemeanor sexual battery, molestation and trespassing, convictions that require he register as a high-risk sex offender. He was released March 31. 
Police said the caseworkers involved in Wednesday’s incident were state employees with a program called Supported Living Services. The program assists adults with developmental disabilities, according to the California Department of Developmental Services website.
