On December 9, 1982, the frozen bodies of cousins Dennis Patrick Alt, 24, and Christopher Alan Schoenborn, 20, were found in an icy field in Plainfield Township north of Grand Rapids, Michigan. Both men, from local farming families, had been attending a horticulture convention at the Amway Grand Plaza Hotel and were last seen alive two nights earlier after having drinks at the hotel bar. Their bodies were partially clothed and showed signs of abuse; autopsies found diazepam in their systems and determined both had been strangled.

Investigators tied the killings to Randy Steven Kraft, a California man who had been at the same hotel. Alt’s car keys were recovered from a hotel room Kraft had vacated, and searches of Kraft’s Long Beach residence turned up a bottle opener belonging to Alt and a jacket owned by Schoenborn. A coded list found in Kraft’s car contained an entry recorded as GR2, which authorities interpreted as referring to the two Grand Rapids victims. Kraft was later indicted by a Kent County Grand Jury for these murders.

Does anyone have memories of Dennis or Christopher, or information about their movements in Grand Rapids around early December 1982?
