Philadelphia police change account of fatal shooting by officer

Officers began pursuing the driver after they said they saw him driving erratically in North Philadelphia. They followed the vehicle as it made several turns before traveling the wrong way down East Willard Street.

After the vehicle parked, officers got out of their patrol car and approached the Toyota Corolla from both sides.

One of the officers tried opening the passenger's door while a partner walked toward the driver's side. The officer on the passenger's side "alerted" the second officer that the driver "had a weapon," Outlaw said.

As the driver turned, the officer on the driver's side opened fire, striking Irizarry multiple times, Outlaw said. He was later pronounced dead at the hospital.

A department spokesperson's original account to reporters at the scene of the shooting on Monday said the driver was actually outside of the vehicle, and had brandished a knife and lunged at an officer when he was shot.

Police recovered two weapons — a kitchen knife and a serrated folding knife — inside the vehicle, Philly Detective Peter Marrero said at the news conference.
