Three separate police shootings are under investigation after law enforcement officers fired shots at people in three different Pittsburgh-area counties in just over 48 hours. 

Pennsylvania State Police troopers are investigating all three police shooting incidents that happened in the city of Pittsburgh, in McDonald Borough, Washington County, and in Grant Township, Indiana County. 

One of the people who was shot by police have died. The other two people were injured and taken to the hospital.

Pittsburgh Police officer and suspect injured in exchange of gunfire 

The first police shooting happened around 1 p.m. on Friday afternoon along Wilner Drive in Pittsburgh's East Hills neighborhood.

Police said Stanley West, 38, was wanted on homicide charges following a deadly shooting that happened at a motel in Robinson Township when officers tracked him to the East Hills.

When officers approached West's vehicle, he's accused of opening fire, hitting a Pittsburgh Police detective in the leg. Detectives returned fire, hitting West multiple times.

West was taken to the hospital in critical condition. An update on his status hasn't been provided.

The officer who was hit with the gunfire was released from the hospital and is expected to be okay.

Because Allegheny County Police officers were involved in the shooting alongside Pittsburgh Police officers, the Pennsylvania State Police are leading an independent investigation. 

Man shot by police officer outside of McDonald Borough bar

On Friday night, the second police shooting within the last several days happened along East Lincoln Avenue in McDonald Borough.

Jeremy Washington is accused of aiming a gun at McDonald Borough's police chief before the chief fired one round at him, shooting him in the arm. 

Police said the department's chief was responding to a call for someone who had been threatening another person that was possibly armed with a gun. 

Washington was taken to Allegheny General Hospital, was last listed in stable condition, and is facing aggravated assault charges in connection with the incident.

Pennsylvania State Police troopers from the Washington barracks are investigating the police shooting.

Troopers said they returned fire, shooting and killing the man, who has yet to be identified.

The Major Case Team from the Troop A with the Pennsylvania State Police is now investigating the deadly police shooting.  

The Troopers involved in the deadly shooting have been placed on administrative duty in accordance with Pennsylvania State Police policy.
