Now when was that?
In 1985, the Texas Attorney General wanted to confirm when Henry Lee Lucas left prison in Michigan. Unfortunately, Michigan only kept files for 5 years. Below is the first page of an affidavit about efforts to figure it out. One source was a "dress out" log: Lucas was measured on 8-21-1975 and issued clothing 8-22-1975, suggesting he was released. "Discharged 8-22-75" was also written on his medical file. That's the date they went with.
