Alvin Melleth

I'm still kind of shocked that he said yes.

From Serial Productions, The Marshall Project, and The New York Times, this is The Last 12 Weeks.

I'm Maurice Shema.

Leading up to his execution date, David Wood's lawyers didn't just contact me.

They tried some of the other usual suspects, who often bring attention to death row cases.

The Innocence Project, Kim Kardashian, among others.

None of it worked, and it's not hard to see why.

This is Detective John Guerrero, formerly of the El Paso Police Department, now retired.

Johnny, if you talk to him for five minutes.

I'm going to let him lay out the basics of David Wood's case.

This was one of the biggest cases of his career, so it's a story he likes telling.

It starts in the late summer of 1987.

A call came in.

Two county employees said they'd been working out in the desert, northeast of the city, when they saw something pretty disturbing.

It was the body of a woman named Rosa Maria Casio.

She was 23 or 24, in from out of town to visit family.

They search the area, and pretty quickly, about 50 feet away, they find a second body, Karen Baker.

She's 20, from El Paso, a mother of three young children.

So the police start looking into both of these deaths.

And then, a month and a half later, a canine team finds a couple more bodies, not far from the first two.
