Francisco Pimentel was 18 when he boarded a train at the Providence Amtrak station on August 8, 1976, en route to Fort Dix, New Jersey, for basic training with the Massachusetts Army National Guard. He traveled to the station with family, friends and fellow recruits but never arrived at his destination and was not seen again after boarding the train.

The circumstances of what happened during the journey remain unclear. Investigators have said something likely occurred before reaching Fort Dix, but no substantial evidence or confirmed sightings have emerged, and his case is classified as endangered missing.

If anyone was on that train or in the Providence station that day and remembers Francisco Pimentel or any unusual events on the trip, investigators would welcome that information.
