Additional information here, in the obituary of one of the men present during the bizarre murder. the morning of Wednesday January 11, 1984 Jack Brown was in his Ypsilanti office on the phone with his son, Jackie, when he said "we've got trouble here" and hung up. Two men had entered the office looking for him, they shot Brown in the neck, closed the other three employees in a closet and fired another shot, this was into the ceiling. Perhaps to frighten the others Despite eyewitness accounts of his attackers and, at one point, a $30k reward, no progress has been made in his case. I read in an archived paper that the Ypsi police told his former wife (mother of their four children) "you give us a why, we'll give you a who"
