THE BRONX - Police are investigating the slaying of two Bronx men who may have been killed in retaliation for a fake money scam.

Police say Sekou Sakor and Ansu Keita, both originally from Liberia in Africa, were each shot in the head last week at a vacant condominium on Long Island owned by former Jets player Jonathan Vilma.

Police officials said investigators believe the victims may have been mixed up in a so-called black money scheme, where unsuspecting victims are sent e-mails saying that they could receive $100 bills smuggled from overseas - stained black to avoid detection - if they purchase a special chemical to wash it off; police say what they end up getting is worthless.

It was unclear how Sakor, 31, and Keita, 32, ended up at Vilma's home, where neighbors reported shots fired on Thursday night. Sakor's body was found Friday dumped in Queens; Keita's body was found in Brooklyn.
