BREMERTON — A man with schizophrenia was sentenced to 11½ years in prison after he pleaded guilty to assaulting his mother last year, a judge said.

Adrian Allan Charvet, 30, pleaded guilty to first-degree assault after he attacked his mother in Bainbridge Island in January 2019, the Kitsap Sun reported Tuesday.

His mother told Bainbridge Island police that she let her son stay at her house knowing he was homeless, but he became violent after demanding money, authorities said.

Charvet punched her, tried to strangle her and forced her to swallow up to 25 Aleve pills before she was able to escape and call for help from a neighbor’s house, prosecutors said.

Charvet was found competent to stand trial after an evaluation, a Western State Hospital psychologist said. He also met the criteria for a diagnosis of unspecified schizophrenia, but his symptoms were controlled while he took prescribed medications, the psychologist said.
