Cops found the remains of a human body buried in the backyard of a Crown Heights home yesterday, after receiving a tip from a source.

Police were directed to a duplex at 657 St. John’s Place, located near Franklin Avenue, yesterday afternoon. There, they excavated the yard and found bones and other remains of a man's body wrapped in plastic. The victim's identity and cause of death are still unknown, though CBS 2 reports that sources believe his death was a homicide, and the remains are currently at the Medical Examiner's office. NBC reports that the body may belong to a man believed to have been killed 10 years ago.

The duplex has reportedly not been lived in for about a year, but a neighbor told 1010 WINS it's a drug den. "I’m really surprised that it’s happening right now, but I’m not surprised,” she told the station. “What used to go on in there. It used to be a crack house. Wherever crack is involved, any and everything goes."

Though the Times says an anonymous caller directed cops to the house, sources told the Post that police were tipped off by Oswald Lewis, an alleged cocaine trafficker who was arrested in August after engaging in a shootout with cops and U.S. marshals at his home in Queens.
