I heard of this story on NPR a week or so ago. Then, yesterday, driving home from Pastors' Roundtable on Issues Etc., I heard an update on the story. So I looked for the New Yorker article. Here it is.
The update yesterday is Texas Gov. Perry removed three of the members of the board reviewing Willingham's case, replacing the chairman with one of Texas' most notorious pro-death-penalty prosecutors. Whether the investigation will even continue remains to be seen.
Read the whole New Yorker article. Did Texas execute an innocent man? It seems like it.
