Case Closed

[Clodfobble]

Investigators lifted bloodstained carpet from Mr. Toole’s white Cadillac. But DNA testing then was not as advanced as it now, and investigators could not tell if the blood was Adam’s.

When a detective assigned to the case in 1994 went to order DNA testing on the bloodstained carpeting from Mr. Toole’s car, the carpeting and the car were found to be missing.

I'm guessing they just found the carpet in some evidence room somewhere, bothered to do proper DNA testing on it, and officially confirmed what everyone already knew.
