Christopher Kerze was 17 and living in Eagan, Minnesota, when he disappeared after skipping school on April 20, 1990. He told his parents he was sick and would stay home; when his mother returned later both Christopher and the family’s blue Dodge Caravan were gone. A note left at home said something important had come up and he planned to return by 6 p.m., with the word lost underlined twice.

The next day a letter postmarked from Duluth arrived saying he had lied to take the car and expressing an intention to end his life, along with an apology. The family van was recovered two days later about 20 miles north of Grand Rapids near a forested area. Christopher was not in the vehicle, and his father’s 20-gauge Mossberg shotgun was inside though no ammunition appeared to be missing. Extensive searches turned up no trace.

Agencies have variously treated him as an endangered runaway; others suspect suicide with the body never found. The case remains open and age-progressed images have been circulated to renew interest. Anyone who knew Christopher or has information about his movements in April 1990 is asked to come forward.
