HAMPTON — The death of a man found injured and unconscious in his Hampton apartment Saturday has been ruled a homicide.

The state Attorney General’s office said an autopsy conducted Monday determined that the manner of 34-year-old Juan Astacio’s death was homicide, but the cause remains under investigation.

Astacio was discovered unconscious and injured after Hampton police responded to a 911 call regarding an incident at his apartment, the Attorney General’s office said.

Officers were called to the apartment Saturday afternoon and at one point reported over emergency radio communications that a man was suffering heavy bleeding from his face.

Astacio was transported to a local hospital, where he was pronounced dead.

The apartment building is located at 87 Brown Ave., which is directly across the street from the Hampton Police Department.

The area around the apartment was taped off Saturday night as local police and the State Police Major Crime Unit investigated the death, which at the time was classified as suspicious. Investigators cleared the scene Sunday.

Neighbors said Astacio lived in Unit 2 and shared the apartment with someone else. They said he had lived there for some time.

“Juan was an awesome guy. We never had a problem with him,” one neighbor said.

Several neighbors said they didn’t know what happened at the apartment Saturday. They said many of the residents who live there tend to keep to themselves.

“I was here all day and I heard nothing,” a neighbor said.

The investigation is ongoing. Authorities are asking anyone with information on the incident to call New Hampshire State Police at 223-4381.
