William Bill A. Henson, 59, of Fairborn, Ohio, was shot to death on January 14, 2015. A U.S. Air Force retiree of nearly 20 years, Henson collected guns and antiques and is survived by his dog Gerda, his parents Bonnie and Robert Henson, two sisters Penny Belzman and Terri Baca, nieces, nephews and other family members.

Raymond Zimmerman, a 17-year-old relative, pleaded guilty to killing Henson; he was shot twice in the head and once in the shoulder. Zimmerman’s plea and sentence—life with the possibility of parole after 18 years—followed a sequence that reportedly included Zimmerman briefly taking a woman hostage while escaping juvenile detention officers. The killing was described as motivated by Zimmerman’s desire for drug money. Another teenager, Robert Winbush, 19, was charged in connection with the murder and was scheduled for trial in July.

Henson’s family and neighbors expressed shock and grief at the loss. Does anyone have memories of William or information about the case that could add context to what happened?
