Henry Louis Baltimore Jr., 21, vanished from East Lansing, Michigan, in late spring 1973 while a junior and honors student at Michigan State University. A talented musician and one of the band’s earliest Black drum majors, he studied social science and music, worked at the university library and planned to become a social worker. He was last seen in a black turtleneck sweater, light-gray slacks and black-and-gray shoes; he stood about 6 feet 1 inch to 6 feet 3 inches and weighed 170–180 pounds.

Three months before his disappearance Henry had been tied to his bed and robbed; he later identified one suspect, Roy L. Davis, who was arrested on that charge. Henry testified at a preliminary hearing on May 24, 1973, and a follow-up hearing was set for June 1. Neighbors recalled a green car and two men pounding on Henry’s door the day he vanished. His 1968 Buick and personal belongings, including keys and money, were left at his apartment; there was no sign he packed to leave.

Records say investigators and the family considered a link between the pending prosecution and his disappearance, and a reward was offered. What details do readers remember about campus life in East Lansing in 1973 that might shed light on Henry’s last known movements?
