At 2 p.m., officers found Swan, who was wanted for a probation violation involving a weapons charge, and chased him on foot. At 4:15 p.m., a Brackenridge police officer saw Swan in the 800 block of Third Street and another foot chase ensued, Kearns said.

Two shootings occurred a few blocks apart during the chase and two officers were shot. McIntire was struck in the head, Kearns said.

Following the shootings, Swan allegedly carjacked a vehicle. 

While in the stolen vehicle, Swan encountered Pittsburgh police detectives, who tried pulling him over. He didn't stop and a car chase ensued before Swan allegedly crashed the car into a housing development area and fled. 

While fleeing from the crash site, he allegedly opened fire on the officers, who returned fire. Swan was hit and died at the scene, police said. Investigators recovered two different handguns, one at the scene of the Brankenridge shooting and another where Swan was killed, Allegheny County police said. 

Investigations will be conducted on all three shootings, including the one that killed Swan, authorities said.

Pennsylvania governor-elect Josh Shaprio called McIntire's death a "devastating reminder of the bravery of those who put their lives on the line every day to protect us."
