So that wasn’t the head of Dr. Sara Tancredi in that box. “Prison Break” executive producer Matt Olmstead told TV Guide that Sara did not die last season and will be returning to the Fox drama.

What changed was…. once we realized that the emotional hook of Season 3 was going to be the death of Sara, when we didn’t get the actress [Sarah Wayne Callies could not agree to a contract] to do it, as soon as we wrote it and shot it, we realized that there was actually a way she could still be alive. Lincoln glanced at the head in the box for a split second. That could’ve been anyone.
