A donation jar for the family of slain Philadelphia Police Officer Chuck Cassidy was stolen yesterday morning from the Dunkin' Donuts where Cassidy was shot in October, a police spokesman said.

Security video shows a man crawling through the drive-through window of the West Oak Lane doughnut shop at about 3:30 yesterday morning.

Once in the shop, he snaked across the floor and stole the jar off the counter. He fled shortly afterward.

The donations were to benefit the slain officer's family. The jar contained about $30 in cash, police said.

Another donation jar for Cassidy's family was stolen by a young man at a Wawa on Tyson and Brous in Northeast Philadelphia around 3 a.m. Sunday, police said.

The man - described by police as a white male in his 20s who was accompanied by a woman - cut the security cord holding the container in place and ran off with it.

The amount of money was in that jar was unknown.

The suspect in the Dunkin Donuts theft is described as a black male in his 30s, wearing a knit hat and a work jacket.

On Oct. 31, Cassidy was shot at the Dunkin Donuts at 66th and Broad in West Oak Lane when he walked in on a robbery in progress. He later died from his injuries.

John Lewis, 21, who was captured in Florida in November, is charged with Cassidy's slaying, as well as five armed robberies. A preliminary hearing for Lewis is scheduled for early January.
