St. Louis (KSDK) - St. Louis police say they fired at least 60 rounds at a man, eventually killing him late Tuesday night.

Police say three officers on patrol noticed the black male pointing a hand gun near the door of the Northway Supermarket in the 5500 block of West Florissant Ave. in North St. Louis. The officers believed they were interrupting a robbery or assault.

They say when they approached the man he pointed the gun at them and they opened fire.The man ran, and the officers chased him on foot. Police say three more times the officers caught up to the man and fired when he pointed the gun at them. Fearing for their safety, the officers fired several rounds of shots at the suspect.

The suspect was pronounced dead at the scene. Police have identified the suspect as 39-year-old Deandra Pye.

No officers were injured.

Police say initially the officer thought one of theman's bullets went through his pants leg, but police say after further examination no bullet hole was found. The officer did feel the bullet pass, causing him to jump.

Police say it is unclear why the man wasstanding nearthe NorthWay Market with the gun.

"It may well be that they interrupted the robbery. But again, we're not really sure," said Capt. Michael Sack with the St. Louis police. "We do have some video from the business that we're going to examine. Hopefully that will shed some more light on what happened," said Sack.

Police also say they were able to interview witnesses who were both inside and outside of the market at the time.
