This is one of Colerain Township’s darkest and most unsettling cases — the trial of Fred Engelhardt, a man accused of murdering his own mother in 2002. What unfolded in the courtroom was chilling, but what lies beneath the surface is even darker.
Engelhardt’s defense made a desperate pivot: arguing he should be convicted of manslaughter instead of murder. His attorney claimed that years of emotional turmoil and psychological pressure from his mother “drove him” to kill her. But prosecutors painted a far more brutal picture — one of rage, violence, and a weapon chosen for maximum destruction.
Police say Engelhardt used a hammer to beat his 57‑year‑old mother to death.
