Gunman who fired at 2 officers is presumed dead, along with 5 relatives, sources say

PHILADELPHIA — After hours of sifting through the charred remains of an East Lansdowne, Pa., home on Thursday, investigators retrieved three sets of human remains and a rifle — the beginnings of their painstaking search for evidence as they worked to piece together what led a resident of the home to shoot two police officers before setting the house ablaze the day before.

It was difficult, “gruesome” work, according to Delaware County District Attorney Jack Stollsteimer.
