Police identified him on Thursday three people killed in West Oak Lane Wednesday afternoon in what authorities say appears to be a murder-suicide sparked by a dispute between neighbors.

Clinton Quarles, 77, and Linda Beeks, 76, were found lying on the steps of their home in the 7300 block of East Walnut Lane with gunshot wounds just before 4 p.m. the police said. A neighbor, Alvinn Berry, 66, who police said shot the couple before turning the gun on himself, was found dead next to them in what appeared to be a self-inflicted gunshot wound head.

The three were next-door neighbors, authorities said, and their homes share front steps.

Quarles and Berry were pronounced dead at the scene, police said. Beeks was still alive when police arrived and was taken to Jefferson Einstein Hospital Philadelphia, where he later died of his injuries, police said.

Neighbors told police the couple had been arguing with Berry, and police believe an argument may have sparked the shooting.

Police said Wednesday that several bags of groceries were spilled at the scene of the shooting and they believe the couple had just returned from shopping when Berry shot them.

The scene of the fire was quiet Thursday morning as the soft sound of light rain pierced the quiet of the tree-lined block. One resident said most of those who lived on the block had been there for decades, most of them pensioners who had nothing.

A neighbor who asked not to be identified out of fear for her safety said she didn’t know Quarles or Berry very well, but remembered Beeks as a friendly woman who was a dedicated gardener.

The woman said she was surprised to hear gunshots Wednesday afternoon, recalling a volley of eight or nine shots, quickly followed by another round moments later.

After the fire subsided, she said, she went outside to join the gathering crowd of onlookers and saw someone being taken from the home on a stretcher.

The woman, who has lived on the block for 25 years, described the neighborhood as a tight-knit community in a relatively safe and quiet part of the city.

Thursday morning, vestiges of the shooting remained. A car parked outside the home Quarles and Beeks shared was riddled with what appeared to be three bullet holes on the right side, and a stray shirt lay discarded in a nearby bush.
