VANCOUVER, Wash. (AP) -- The Clark County medical examiner says a prisoner at the county jail who died in February suffocated as he was being restrained by officers.
The cause of death was released Wednesday for 28-year-old Marius Asanachescu, who was being held for investigation of second-degree assault.
The medical examiner's office said he suffocated because officers who were trying to keep him from hurting himself compressed his chest and prevented him from breathing.
The office also said psychosis was an underlying cause and obesity a "significant condition" leading to the death.
Vancouver police detectives continue to investigate.
The Clark County Sheriff's Office said Wednesday that its internal affairs unit is conducting its own investigation and reviewing any applicable policies and procedures.
The officers involved were initially put on administrative leave but have since returned to work.
