The hostages of the Philadelphia killer were "successfully evacuated".
CNN reports this, citing some sources, according to which the attacker is still inside the house in Trenton, New Jersey.
Andre Gordon, the man who killed three people near Philadelphia is homeless.
He reports it to the Pennsylvania police.
"We have had some contact" with Gordon "in the past but minor things", the agents add, underlining that the killer had an AR-15 type rifle and perhaps other weapons.
