OGDENSBURG -- City police have made an arrest in the May homicide of a St. Lawrence Psychiatric Center patient, and the suspected is being held without bail.

Jose D. Miranda, 64, of Rochester Psychiatric Center is charged with criminally negligent homicide in the death of Robert Harrienger.

Miranda, who at the time was also a psych center patient, is accused of assaulting Harrienger and causing a head wound that later killed him, police said.

City police say they responded to a call at 5:57 p.m. May 12 of a patient-on-patient assault in the Trinity building on the psych center grounds. They say they discovered Harrienger there with a head wound. He was taken to Claxton-Hepburn Medical Center and from there sent to SUNY Upstate Medical Center, Syracuse, where he died a few hours later. The Onondaga County Medical Examiner’s Office performed an autopsy and ruled the death a homicide, police said.

Miranda was arraigned in St. Lawrence County Court and sent to the county correctional facility without bail.
