Jimmy was married with 4 kids (including Tamina and Deuce) at the time and allegedly changed his story multiple times.
He initially said they were playing, and he had shoved her earlier in the day, but later said ALL 5 misunderstood him and that she had actually hit her head by accident when she slipped when he stopped to piss at a roadside bathroom.
Considering that the victim had severe brain injuries and lacerations and bruises upon most of her body, police realized his shit stank (32 years later...) police were like "GOT 'EM!" and charged him with murder.
Also, he claimed in his autobiography that he'd never hurt her, but allegedly had been arrested for beating her a month prior to her death.
