A 28-year-old immigrant working at RC Petroleum in East Tremont was brutally shot to death Tuesday night by a gun-wielding man on a bicycle looking for cash, video surveillance released by the NYPD shows. According to commissioner Ray Kelly, the suspect went to the station and found "the victim here counting money in a small office. There’s a struggle, he shoots him, he falls down, he shoots him again. He goes through his pockets and drags the body out of the office." All told, the gunman and his accomplice got about $200 in the deadly encounter.

Now the police are offering a $12,000 reward for anyone with information on the murder of the attendant, 28-year-old Gambia-native Lamin Sillah, who was in the States studying to become an accountant. "He was a beautiful guy. He’s a very hard worker, a very good Muslim," recalled his uncle, Alhagie Ebou Cham, president of the United Gambians Association. "He came here for his education, a better opportunity for that over here."

Sillah, who was almost at the end of his shift when he was shot, leaves behind a wife and a large family back home. "He was the head of the family," his roommate here recalled of his slain friend. "This is a great loss to many people. He was supporting a lot of people."
