Episode 1 of “The Last 12 Weeks,” a podcast from The Marshall Project, Serial Productions and The New York Times, starts with an unusual email.

In late 2024, a defense lawyer named Greg Wiercioch wrote to me, asking me to cover the case of his client, David Wood. Wood had been charged with six murders in El Paso and had been on death row for more than 30 years.

Now, after losing all his appeals, Wood was facing execution. The lawyer had enlisted a team of colleagues to make one final push to save his life. They planned to argue that Wood, one of Texas’ most notorious serial killers, was actually innocent. They had several months.

I asked the lawyer if I could follow his team around in the run-up to the execution, to watch their frenzied efforts to stop it. He had a million reasons to say no. I’m still a bit shocked that he said yes.

He has maintained his innocence for nearly four decades; Greg Wiercioch, a law professor at the University of Wisconsin-Madison, is the lead attorney on Wood’s case; Jeremy Schepers is a supervisor at the Federal Public Defender’s Office for the Northern District of Texas, and is one of Wood’s lawyers; George Hall says that El Paso police encouraged him to falsely claim that Wood, who was incarcerated with him, had confessed to killing six girls and women.
