One of the undercover cops who shot and killed an armed Queens teen fired his weapon eight times, said Police Commissioner Ray Kelly, who insisted it’s too early in the investigation to call the multiple gunshots excessive.

In all, Dashawn Vasconcellos was struck by 11 of the 15 bullets fired Saturday night by cops who reportedly identified themselves before the 18-year-old pointed a loaded handgun at them.

Kelly said the shooting would also be reviewed by Queens DA Richard Brown who yesterday said, “On the surface, the shoot looks clean.”
