A patient at the Hawaii State Hospital was arrested Monday evening after a nurse was fatally stabbed on the grounds of the psychiatric hospital in Kaneohe, Honolulu police said.

Police and Honolulu Emergency Services responded to a 5:21 p.m. for an assault. Emergency responders found a 29-year-old man with multiple stab wounds and the victim was pronounced dead at 6:02 p.m.

Police arrested the suspect, a 25-year-old man, for suspicion of second-degree murder.

Police said the investigation is ongoing and charges will be sought with the state Department of the Attorney General. The suspect remains in custody.

State Department of Health Director Dr. Kenneth Fink issued a written statement after midnight, saying, “We are extremely saddened to report that an incident on Hawaii State Hospital grounds today took the life of a member of our Hawaii State Hospital staff. Our thoughts tonight are with his loved ones.”

He said the patient had been discharged from the State Hospital in August but was transitioning to the community through the State Operated Specialized Residential Program.

“On-site State Hospital leadership immediately responded to ensure the safety of residents and staff,” Fink said. “Deputy Director for Behavioral Health Marian Tsuji, Hawaii State Hospital Administrator Dr. Kenneth Luke, and I arrived on campus this evening to support operations and offer emotional support to staff. We are working with law enforcement to support their investigation into this matter and will provide updates as they become available.”
