Joseph Grasher was 21 when he vanished after attending a birthday party in the 1000 block of Poyntz Avenue in Manhattan, Kansas, on August 22, 1981. At some point that night he left the gathering in his red van with 26-year-old Stephen Hammerle and two other people. That departure is the last confirmed sighting of both Grasher and Hammerle; neither man nor the red van have been found.

The circumstances of their disappearance remain unclear and the Riley County Police Department has not reported a major breakthrough. Family, friends and the local community have kept both cases alive through outreach and social media, including a Facebook page titled Missing: Joseph ’Joe’ Grasher and similar efforts for Hammerle. There is limited public detail about what happened after they left the party.

Does anyone who lived in Manhattan, Kansas, in August 1981 remember seeing a red van or have information about that night?
