But even as Amy cast doubt on her husband, she handed him a lifeline in the form of an alibi.

She told investigators that they were home that evening.

Amy was in the bath while Dave was watching Teenage Mutant Ninja Turtles.

She estimated that she was in the tub from about 7.40 p.m.

to 8.40 p.m., and she could hear the TV from the bathroom.

What she couldn't say, though, was that she ever saw Dave.

Amy told investigators that she never left the bathroom, therefore she never physically put eyes on him watching television.

However, both of them said that the way they'd found out about the incident and had known to go be with Dawn was because Dave's mother had overheard a call from dispatch on the police scanner and she rushed over to tell them.

This account would make it hard to believe that Dave could go to the Mathers, kill Tom, get home, clean up, and be sitting down watching Ninja Turtles like nothing happened.

And if he did that, for what?

Besides the jokes among friends, police could never find a motive.

And as far as we could tell, Dave and Amy are still together to this day.

Oh, and by the way, according to the police file, none of the guns that Dave voluntarily turned over were a match to the weapon that killed Tom.

We reached out to both Dave and Amy, but they declined to comment.

The thing I really couldn't piece together in regard to investigators' suspicion of Dave is how they got there in the first place.

I mean, sure, there's some eyebrow-raising stuff once him and Amy are interviewed, but, like, what even brought it to that?

Because police went into those thinking that Dave was a suspect.

Now, Amy says in an interview that when they both arrived to see Dawn, right as EMTs were getting there, before anyone could settle around her, Dawn immediately grabbed and hugged Dave.

He returned the hug and told her everything was going to be okay.

So maybe one of the EMTs saw that and thought it was odd.
