The Tarrant County District Attorney’s office has notified defense attorneys for as many as 40 other murder suspects there are questions about Krouse's credibility.
"The way I look at it, it's kind of like the grandfather's clock that strikes 13,” said defense attorney Christy Jack. “It calls into question all that came before."
Jack is a former prosecutor who represents a murder suspect awaiting trial. Dr. Krouse did the autopsy in his case.
"Anytime a professional's proficiency is on the line and you've just been handed what could be information that calls into question their expertise, it's a goldmine as a defense attorney,” she said.
