(Hamilton)---Monday marks a sad anniversary for the City of Hamilton. Easter Sunday March 30, 1975, James Ruppert shot and killed 11 members of his family, including his mother, brother, sister-in-law, and 8 neices and nephews at 635 Minor Avenue. The killings were at that time the worst mass murders in American history. The late John Holcomb was Butler County Prosecutor at the time. He told WMOH during a 1996 interview it was "the most shocking day of my life to walk into that crime scene down there, and see all of those dead bodies of those beautiful children on that floor, in pools of blood." Ruppert, who was spared the death penalty after trials in Hamilton and Findlay, is now 80, and is serving two life terms in the Allen Correctional Institution near Lima. A parole hearing is set for next month.
