PENN HILLS, Pa. --

Authorities have released the identity of a police officer shot and killed while responding to a call Sunday night in Penn Hills.

Officer Michael Crawshaw, who had been on Penn Hills' police force for two years, was shot and killed shortly before 8:30 p.m. after responding to a call at a house along Johnston Road.

Penn Hills police Chief Howard Burton said Crawshaw parked his police cruiser two to three houses away from the scene before he was shot. Burton said he isn't sure whether Crawshaw was responding to shots fired or a domestic disturbance call.

Burton said the officer was waiting for backup in the police car when he was shot.

A man who police initially suspected of shooting and killing Crawshaw using an assault rifle was questioned and released.

Originally, police identified Kijafi Fuqua, 27, as a suspect in the case, Channel 11 News reporter Jodine Costanzo said. However, Fuqua told Channel 11 News that his friends called him after hearing his name on television, so he drove to the Clairton Police Department to clear his name.

Police questioned and released Fuqua but did not elaborate any further on the case.

"They slandered my character," Fuqua told Channel 11 News as he left the Clairton Police Department. "They put AKs to our heads. Put my girlfriend on the ground with no shoes on. Nothing to do with this. I was at home with my kids. I don't know nothing about Penn Hills."

Crawshaw was taken to UPMC Presbyterian Hospital, where he was pronounced dead.

Allegheny County Police Superintendent Charles Moffatt said one person inside the residence was also killed. The medical examiner identified that person as 40-year-old Danyal Morton.

Neighbors said they heard shots fired in the area and said the suspect drove away in a dark colored Jeep Cherokee.

At first, Channel 11 News was told police began searching for a vehicle with license plate HFC-6470. Later, Channel 11 confirmed the plate number in question was HCF-6470. It is unclear at this time whether the license plate confusion led to Fuqua being named a suspect.

Shortly after Fuqua went to the Clairton Police Department, police pulled over a woman driving the Jeep along Route 837 near St. Clair Street. The woman, police said, dropped the man off at the station.

Allegheny County homicide detectives are working with the Penn Hills Police Department to investigate.

Earlier this year, three Pittsburgh police officers were shot and killed while responding to a domestic dispute call in Stanton Heights.

Officers Eric Kelly, Paul Sciullo II and Stephen Mayhle were killed during the April 4 standoff.

Richard Poplawski, 23, is charged in the killings.
