Jack Libardo Jimenez, 20, vanished from Mastic Beach, Suffolk County, New York, on the evening of May 21, 1998. He was seen about 10:30 p.m. in front of the D&K Deli near Neighborhood Road and Oakwood Drive getting into a vehicle described as possibly a black truck or a black Ford Bronco with multiple occupants. Earlier that night he had been visiting a female friend and was seen walking home before the vehicle arrived.

Jack is described as a biracial or Hispanic male, 5 feet 8 inches, about 183 pounds, with black hair, brown eyes, a scar on the left side of his forehead, a pierced nose and pierced tongue. He was last seen wearing a white Tommy Hilfiger shirt, blue jeans, a black leather winter jacket and brown Lugz boots. His beeper and wallet were later found in the room he rented; friends reported seeing a shirt believed to be his, stained with what appeared to be blood, on a nearby beach but police reportedly could not locate it after being notified.

A letter Jack sent to a cousin in Colombia about a week before he disappeared said he was in some kind of trouble and mentioned he would be at the lighthouse. The investigation remains open with the Suffolk County Police Department. Did anyone in Mastic Beach at the time see that black truck or Bronco, or recognize the people who might have been in it?
