An ex-con from Brooklyn was charged with murder on Wednesday, for a double-slaying on Staten Island last month, officials said.

Ricky Dennis, 32, was arraigned and ordered held without bail for the Jan. 24 killings of Michael Genovese, 57, and Carl Clark, 52, in the Dongan Hills neighborhood of the island.

Dennis was also charged with gun possession.

The victims were shot in the back of the head at Universal Merchant Funding, a loan business at 124 Buel Ave. that Genovese owned and where Dennis used to work, officials said.

“The defendant in this case is charged with savagely gunning down two people in cold blood,” Staten Island DA Michael McMahon said.

“My prosecutors and I will work tirelessly to ensure justice for both the victims of this heinous crime and their loved ones and keep Staten Islanders safe.”

Dennis‘ car matched the description of one at coming and leaving the murder scene, law enforcement sources said. And his wheels were recorded coming over and going back at the Verrazano-Narrows Bridge a little before and after the slayings, sources said.

Dennis had been released from federal custody in September for a 2005 gun store robbery in Pennsylvania.

After leaving court in Staten Island on Wednesday, he was turned over to feds who are holding him on an unrelated parole violation.
