A man was shot to death outside his house Wednesday afternoon in the Crestmont section of Abington Township, police said.

The 73-year-old man was killed about 1:50 on the porch of his home on Prospect Avenue, about a mile from Willow Grove Park mall, authorities said.

Witnesses told police the gunman drove away in a silver Dodge minivan. Minutes later, officers stopped a vehicle matching the description in the 1500 block of Washington Avenue, a few blocks away.

The driver "refused to show his hands," Deputy Chief John A. Livingood said Wednesday afternoon. "And at one point he pulled out a gun, and he apparently shot himself."

Police fired no shots, Livingood said.

The suspected gunman and the victim were taken to Abington Hospital-Jefferson Health. The suspect was in critical condition late Wednesday. An autopsy on the victim is scheduled for Thursday.

Abington Township police and the Montgomery County District Attorney's Office are investigating. Authorities ask anyone with information to call Abington police at 267-536-1100, Option 3, or Montgomery County Detectives at 610-278-3368.
