An investigation is underway after a man armed with a knife was shot and killed by Pittsburgh Police officers in the city's Greenfield neighborhood.

The deadly police shooting happened at a home along Murray Avenue just after 10 p.m. on Wednesday night. 

Allegheny County Police said that Pittsburgh Police officers were called to a domestic disturbance, and when they entered the home, they were confronted by a man inside a stairwell who was armed with a knife. 

Police said two officers then fired their weapons and critically wounded the man, who was taken to the hospital and later pronounced dead. 

The Allegheny County Medical Examiner's Office has identified the man as Matthew Foster, 24, of Moon Township.

No officers were injured during the shooting, a Pittsburgh Public Safety spokesperson said.     

"Two officers ended up firing their weapons while they were on the stairs, a male subject was wounded, and the officers tended to the subject," said Allegheny County Police Superintendent Chris Kearns. 

For the residents of Murray Avenue, this is anything but normal, and they say that they're surprised. 

"Our neighborhood is so face, the security here is very safe," said Kristin Jakunowski. "In the store, everywhere we go, I've never had a problem, but times are getting tough right now." 

"Especially around these parts, this is like the safest part of Greenfield and Hazelwood, so to hear it's kind of surging up a little bit is a little off-putting," added Anthony Jones. 

Detectives from the Allegheny County Police Homicide Unit are leading the investigation into the deadly police shooting.
