“Garcia was the mastermind of a criminal scheme — basically, they were robbing drug dealers,” says federal prosecutor Kevin Brenner.  “They were using a confidential source in a way that was against Philadelphia police protocols.  And they were using the source to set up drug dealers who they would then stop, search, and ultimately rob of money they recovered from them.”

Garcia, who blamed greed and his own Percocet abuse, also admitted selling heroin that he had obtained from another source.
