Daniel DeGennaro, 56, a local songwriter, guitarist, and singer, was found dead of a single gunshot wound to the chest Wednesday night at his home in Levittown, authorities said.

Bucks County District Attorney David W. Heckler said Thursday that a man living in the same house as DeGennaro discovered the musician moments after the shot rang out.

The man ran to a neighbor's house, and the two returned to DeGennaro's home, where they called police.

Bristol Township police found DeGennaro dead at the scene, Heckler said, adding that police and Bucks County detectives were investigating the shooting.

"It is obviously being viewed as a suspicious death," Heckler said, though DeGennaro's death had not yet been labeled a homicide. An autopsy is scheduled for Friday.

DeGennaro toured with Kingfish, a band that counted former Grateful Dead member Bob Weir as a member. According to his website, DeGennaro also performed with Clarence Clemons, saxophonist with the E Street Band, who died in June.
