Do You Know Why d'Angelo Committed the Crimes?

Many have questioned how D'Angelo committed the crimes without his wife Sharon knowing. She says he gave a valid reasons for being away from home on the nights of the attacks, such as working or going pheasant hunting. Although the couple separated in 1991 and Sharon was a family lawyer, she didn't file for divorce until one year after D'Angelo's arrest. It's an unusual situation that someone so well-versed in the divorce process has chosen not to have completed that process, and it becomes suspicious.
