Four shots fired by NYPD officers at a knife-wielding suspect in Midtown Manhattan this week didn't penetrate his jacket -- which was not bullet resistant.
Officials are now checking the officers' weapons and ammunition for malfunction following the incident, according to The New York Post.
A sergeant and an officer fired a total of nine rounds at 46-year-old Garry Conrad Wednesday, killing the man after he refused to drop the knife he was approaching them with at West 49th Street and Eighth Avenue.
Sources told the newspaper that four of the bullets got lodged in his Carhartt jacket.
While the incident doesn't appear to be pattern, the 9mm guns used by the officers will be looked at.
"I have not heard anything like this. There would be no reason for it," John Cerar, a retired NYPD deputy inspector who headed the NYPD's Tactics and Firearms Section from 1985 through 1994, said. "There would have to be some kind of defect. I would certainly look at the ammunition."
Cerar added that while there could be a defect in the weapon, a defect in the ammunition was more likely and that an investigation is necessary.
