A man who died in a crash on a Virginia road in 1995 left few clues to his identity behind: a star tattoo on his arm, two Grateful Dead ticket stubs and a note addressed to someone named Jason.

Online, the young man became known as “Grateful Doe” as composite images circulated last year. Thanks to some amateur detective work, he has now been identified as Jason Callahan, a 19-year-old from Myrtle Beach, S.C., officials in Virginia confirmed to The Associated Press on Thursday.

Jason’s name had been circulating among online communities of Deadheads, as well as among online sleuths.

The anonymous user greymetal began circulating the composite on Imgur a year ago and posted an update after someone provided photos of a former roommate and Grateful Dead fan named Jason who looked very similar to the composite.
