Channel 4 is reporting the following:
The man with the information, Jon Brawner, has a record that sends up all sorts of warning signals. He says he didn't kill Glasgow but knows who did. Motive? Not given. One of several complications: Authorities once searched the place pinpointed by Brawner but came up with nothing. Channel 4 indicates there'll be another search. Glasgow's car and phone were found at Petit Jean State Park. He was last seen leaving his home for work early the morning of Jan. 28, 2008. No trace of him has emerged.
