Philadelphia Police Commissioner Richard Ross said they will be meticulous in doing so as the scene has proven to be unique.

“In order to proceed now in the legal aspect of it, we have to do everything we’re supposed to do,” Ross said. “Dot every I cross every T. It’s one of the most extensive scenes I’ve seen in a while.”

The commissioner confirmed an AR-15 rifle was recovered from the home, the weapon Hill allegedly used to fire on officers. Officers also found other handguns.

“We also found other handguns inside of there, and as I understand it, he was telling people he was heavily armed and not going back to prison,” Ross said.

With police cars blocking his street and officers crouched behind cars, Nicetown-Tioga resident Ken Unity says at first, he was confused about what was happening outside of his home Wednesday.

“I see a lot of police here, ducking behind vehicles and then when I come up on the step ‘bang, bang, bang’ and I run inside,” Unity said.

Unity took out his cell phone and captured officers taking cover and calling out instructions about hostages in the violent standoff.

Next door, Eric Garrity and neighbors in his apartment building watched every second of the action on a live stream form his home security system.

“This was especially violent so you don’t get to see it that often, stuff like that up front, and I guess that’s a good thing,” Garrity said.

Despite the bullet holes in their homes, no innocent bystanders were hurt as police engaged in a seven-and-a-half-hour standoff with the gunman.

Hill has an extensive arrest record dating back to the early 2000s.

“He was well known to the police. The police in Southwest knew him very well. Known him to be involved in the drug trade and shootings,” Ross said.

Ross says Hill’s family made it clear to the commissioner, he was always interested in gun play.
