Fatal garden party shooting of five people - including pregnant woman - was 'planned'
The fatal shooting of five people, including a pregnant woman, at a Pittsburgh garden party was a planned, calculated attack, prosecutors have said.
One of the gunmen used a handgun to steer the victims towards the house's porch, said Allegheny County district attorney Stephen Zappala, where a second gunman picked them off with an AK-47-style rifle. He said the victims were shot in the head.
The five were killed late on Wednesday during the party in Wilkinsburg. Two others are in a critical condition.
Mr Zappala said as many as 15 people had been at the party and that police are searching for at least two suspects. The motive is not known.
Earlier, a medical examiner released the identities of the five people killed in the shooting. The victims were 35-year-old Jerry Shelton, 37-year-old Tina Shelton, 27-year-old Brittany Powell, 25-year-old Chanetta Powell and 26-year-old Shada Mahone.
The medical examiner said Jerry Shelton, Brittany Powell and Chanetta Powell were siblings.
A neighbour said he saw at least three children run onto the porch screaming "Mommy! Mommy!" after the shooting.
Robert Morris, a 15-year-old who lives across the street from the home, said it was "terrible".
He and his father, Carl Morris, said a black Labrador retriever that had been shot in the tail ran to their house after the shooting.
They said a young woman and her child lived at the home.
Another neighbour, Mike Jones, said violence is rare in the neighbourhood.
