Legal experts comment on Winkler case

Could Mary Winkler have been protecting her children from some unknown danger? Memphis attorney Dewun Settle believes that may become the defense strategy.

"You never know what's going on behind closed doors and these are the kinds of things that can create a defense for a case like this," says Settle.

Right now, Winkler's defense team is likely nailing down their client's story, speaking with others who can shed light on her marriage to the murdered minister, and considering a mental health evaluation.

"There's certainly the possibility there's a defense of insanity, self-defense, who knows?" asks University of Memphis law professor Barbara Kritchevsky.

Mary Winkler was expected to plead not guilty, despite reports of a confession last week.

"There's the possibility that somebody would argue the confession was coerced, that the person was not in sound mental state," says Kritchevsky.

The confession and the crime itself have been the talk of Selmer. That's why our experts believe the defense team may eventually argue for a change of venue.

"There's going to be people coming down on both sides of the fence very firmly," says Settle. "So her ability to get a fair trial in Selmer may be compromised," he adds.

No matter what happens, it appears this case will continue to fascinate.
