The NYPD is hoping new surveillance footage could lead them to the suspect responsible for the death of an 83-year-old man who was badly beaten inside his Greenwich Village home more than two years ago. 

Police are still looking for the man who beat and robbed Joseph Sibilla inside his home on West 12th Street on April 29, 2011. Sibilla spent more than two weeks in the hospital before he died from his injuries. 

Police had responded to a 911 call of a man assaulted and found Sibilla, beaten and in serious condition. His wallet had been stolen. 

Sibilla, once a pilot and psychologist, was affectionately known as "Joe" in his neighborhood. He belonged to a singing and dancing seniors' group called "The Showstoppers." 

"Who would do such a thing?" asked friend Nancy Kremsdorf after his death in 2011.  

The man who attacked Sibilla is described as 35 to 40 years old and 5 feet 7 inches tall with a thin build. On the day of the attack, surveillance video shows him wearing a dark coat, blue jeans and a blue and green baseball cap as he exits the building. Footage released Tuesday shows the man walking in the area in the same clothes. 

If you recognize the man or have information on the killing, contact Crime Stoppers at 1-800-577-TIPS or www.nypdcrimestoppers.com.
