Margo’s ex-husband, Douglas Prade, had been a cop with the Akron Police Department for 30 years at the time of her murder. He was ultimately tried and convicted of her murder all because of what APPEARED to be a bite mark on her arm. Interestingly, a bite mark is not as reliable as DNA or fingerprints.
The odd thing about this bite mark? It was left by the lower teeth only. Douglas does wear dentures for his upper teeth. But why would he bite her that way when it would be so obvious it was him?
