Community mourns as police seek ambush suspects
Two males who were transported to the hospital are in critical condition, and one female is in stable condition.
Allegheny County Police said evidence indicates one gunman fired from an alley behind the residence, and another from the side or backyard of an adjacent home. A police officer responds to the scene of a deadly shooting in Wilkinsburg, Pa., Thursday, March 10, 2016.
The Allegheny County Medical Examiner has released the names of the five adult victims, three of whom - Brittany Powell, Chanetta Powell and Jerry Shelton - were siblings.
Police are considering drugs as a possible motive, however "everything is on the table", Moffatt said.
Zappala said it was the most brutal attack he's seen in his 18 years as a district attorney.
"This is unheard of", Jones said of the ambush, shaking his head as homicide detectives milled about in the yard and alley. He said gunshots came from two distinct locations but police don't believe anyone at the party fired back. "As a community, we must say enough is enough and providing information on this senseless shooting can be our first step to stopping the violence in our communities". "You got to stop it now", she said. Four of the dead were found on the tiny back porch.
Zappala added the shooters weren't "just squeezing off shots".
Lt. Andrew Sherman says a "backyard party" was underway at the time of the shooting. He says an accomplice with a rifle then shot the victims in the head as they ran back to the house for cover.
"There's no indication that this was either a stash house or they were running an operation out of here", he said.
Allegheny County District Attorney Stephen Zappala says one of the shooters used a handgun to steer the victims toward the house's porch, where a second gunman picked them off with an AK-47-style rifle.
The shootings occurred in the working-class borough of Wilkinsburg in Allegheny County, which has a population of about 15,000 and is some 8 miles (13 km) east of Pittsburgh.
The gunmen fled on foot.
Authorities say a party was going on at the home when the shooting occurred.
After the shooting, groups of residents gathered on the street, some of them sobbing and saying they lost family members.
"Communities like Wilkinsburg - and other towns and cities across Pennsylvania like Pittsburgh, York, where I live, and Philadelphia - know all too well the horrific nature of gun violence in their neighborhoods", Wolf said.
