Four killed and two children injured after Philadelphia mass shooting

A suspect is in custody after four people were killed in a mass shooting in Pennsylvania.

The suspect opened fire in the Kingsessing area of Philadelphia on Monday night in what’s been identified as the 29th mass killing in the US of this year.

The four victims have not yet been publicly identified but police commissioner Danielle Outlaw said they were all male, three aged 20-59 with one aged between 16 and 21.

Two boys, aged two and 13, were injured during the shooting and are currently in a stable condition in hospital.

Dozens of shell casings were found, and officers heard more gunfire as they attended to victims.

The suspect was arrested in an alleyway at the scene. He had a bulletproof vest, multiple magazines, an AR-type rifle, a handgun, and a police scanner.

The suspected gunman has been identified as a 40-year-old man, and there is another person in custody in connection with the attack.

Commissioner Outlaw said: ‘At this point all we know is that this person decided to leave their home and target individuals.
