Dramatic new video shows the moment police officers opened fire on James Patrick Dillon, ending his violent rampage in Queens on Sunday.

The footage, captured by a witness watching from his window in Astoria, shows officers with their guns pointed at Dillon, 23, while ordering him to drop the knife police say he used to fatally stab a man at a nearby liquor store and slash another woman’s head.

When Dillon begins to walk toward them with the knife, the officers are forced to shoot him several times before cuffing him.

Dillon is currently listed in critical condition at Elmhurst Hospital.
