PITTSBURGH (KDKA) — A key witness in the case against a pizza shop worker accused of attacking a woman has died.

James Blackburne captured video of the violent confrontation between a woman and a worker inside Pizza Milano back in January.

But Blackburne died last weekend in a car crash on Frankstown Avenue.

The alleged victim’s lawyer planned to call him as a witness in the case, but says they still have the video and it speaks for itself.

However, he says he would have liked to have had Blackburne testify under oath.
