Tyler Mook's accidental call to 911
About a year after his ex-wife's disappearance, Mook apparently butt-dials 911, not realizing the operator was listening and recording the call for 22 minutes. The conversation with his father is difficult to hear, but Mook seems to be talking about that the night Shelley disappeared. Listen to excerpts of the call. "48 Hours" has more on the case Saturday, May 26 at 9 p.m. ET/PT on CBS.
