LANCASTER, Pa (WHTM) – Officers from Lancaster Bureau of Police say there was an officer-involved shooting after police responded to a domestic disturbance on the 300 block of Laurel Street at 4:15 this afternoon.

The shooting was captured on the officer’s body camera.

The Lancaster County District Attorney’s Office says a first look at the footage shows that when the officer went to the house, 27-year-old Ricardo Munoz immediately came out outside, running toward the officer with a knife above his head in a threatening manner. That’s when the officer fired.

“While they’re conducting the criminal investigation, we’re going to be conducting our administrative personnel investigation to make sure that policy and training and use of force was properly followed,” said Lancaster Bureau of Police Chief Jarrad Berkihiser.

Berkihiser is calling for everyone to maintain peace and allow the investigation to play out.

“Any loss of life regardless of how it happens is devastating. It’s devastating for everybody involved. It’s devastating for a police department, the families and our community,” Berkihiser said.

Dozens of people packed Laurel Street to protest the shooting. Then many marched to the police station, blocking part of West Chestnut street for several hours.

Isaac Etter with safe house Lancaster says the protests are a result of months of pent up frustration.

“We had a lot of issues in June with the Lancaster City Police and I think to see the lack of change in both the police force and in the city has led to the unrest that is today,” Etter said.
