Former officer Juan Acosta, 34, pleaded guilty to conspiracy to distribute drugs, extortion, and illegal use of a firearm. He and a partner were accused of selling cocaine throughout the city since 2005, and Acosta was also accused of using his position as a beat cop to rip-off a drug courier in 2005. He went down after getting caught in a sting last November where he took $15,000 from a government witness to transport 10 kilos of cocaine from a Long Island warehouse to the Bronx. He faces up to life in prison when he is sentenced July 22.

In Lake Wales, Florida, a Polk County deputy sheriff was arrested last Friday on charges he provided confidential information to a woman who was being surveilled as part of an investigation into a local drug trafficking operation. Deputy Sheriff Joseph Murphy, 41, a 16-year-veteran, admitted to accessing the state Driver and Vehicle Information Database to run a license tag for the girlfriend of the drug ring leader, who said she was being followed by a vehicle. That vehicle turned out to be an undercover police vehicle indeed following the girlfriend, and her call to Murphy was recorded as part of the investigation into the ring. He is charged with unauthorized use of a computer, a third-degree felony, and has been suspended without pay pending termination.
