PORTAGE, MI -- The Portage Department of Public Safety has released dash cam footage from its police cruisers involved that were involved in a chaotic chase May 14 that ended with the fatal shooting of Sean Michael Pelletier.

In the footage, Portage police can be seen pursuing an Acura sedan heading westbound on Milham Avenue while occupied by Aaron Joseph Pelletier and his brother, Sean Michael Pelletier. The Kalamazoo Public Safety officers, Kalamazoo County Sheriff's deputies and Michigan State Police were also involved in the chase.

Once cruisers head off the vehicle near the entrance to Anna's Vineyard Apartments, gunfire can be heard.

The wall of police vehicles causes driver Aaron Pelletier to circle around police and into the complex.

As police vehicles continue pursuit into the apartment, numerous gunshots can be heard. By the time the first Portage police cruiser reaches the scene, Sean Pelletier has exited his vehicle and can be seen in the distance, upright on the ground.

Police opened fire after Sean Pelletier exited the car with what investigators described as a "high-powered military-style rifle," according to Michigan State Police.

Another round of gunfire erupts before Sean Pelletier completely falls to the ground and drops his weapon. Police then converge on the suspects.

Aaron Pelletier remains at critical at Bronson Methodist Hospital.
