On March 30, 1975, 16-year-old Michael James Ruppert of Hamilton, Ohio, was killed during what became known as the Easter Sunday Massacre. His uncle, James Urban Ruppert, fatally shot 11 members of the family in their home; Michael was among the victims.

Authorities later arrested James Urban Ruppert and charged him with 11 counts of aggravated murder. At trial he was found guilty on two counts and declared not guilty by reason of insanity on the other nine; he received two consecutive life sentences and was held at Allen Correctional Institution and later at Franklin Medical Center as his health declined. Reports indicated the motive involved revenge for perceived lack of affection from his mother and brother and possible psychosis and paranoia.

The massacre drew wide attention for its scale and its links to family dynamics and mental illness. If anyone knew Michael or the family and has memories or information to share, please contribute.
