Cellphone video shows the moments leading up to a fatal police-involved shooting in West Haven.

The video was shared with News 12 by construction worker Eddie Pagan, who says he was working close to the scene when it happened.

The incident started on Main Avenue in Norwalk Wednesday outside of the Verizon Wireless store, where police say a man used a knife to carjack a person inside of a white sedan.

State police pursued the suspect's car on I-95 and a chase began.

The chase was caught on state traffic cameras, and showed the driver colliding with other vehicles before ending up in West Haven underneath Exit 43.

Police say the driver of the stolen car also intentionally struck officers’ cruisers.

The vehicle was eventually stopped in traffic on Campbell Avenue in West Haven, about 30 miles away from where it was stolen.

State police say an altercation occurred with the suspect before officers opened fire on the man.

He was taken to Yale New Haven Hospital where he was later pronounced dead. Police have since identified the victim as Murbarak Soulemane, 19 of New Haven.

Pagan tells News 12 he and other witnesses didn't know where the shots were coming from, but at least seven shots can be heard in the video before Pagan gets startled and jerks the phone away.

Troopers say they found a knife inside of the stolen car.

The suspect and officers involved have not been identified, and police say they plan on releasing body camera footage from officers soon.

This is the second fatal police-involved shooting in Connecticut this month.
