Real Name: Lacretia Gail Jordan and Dawn Marie Lamont Nicknames: No known nicknames Location: Magnolia, Texas Date: July 13, 1991 Case
Details: On the night of July 13, 1991, Gail Jordan and Dawn Lamont were driving when Dawn's pickup truck broke down seven miles from Magnolia, Texas. While they were walking to get help, they were struck by a hit-and-run driver, and their bodies were found several hours later. The person responsible has never been located.
Suspects: Based on a broken headlight found near their bodies, police believe the killer's vehicle was a 1983 or 1984 Chevy Suburban or Blazer, Chevrolet Van or Pickup truck.
Extra Notes: The case was featured as a part of the September 22, 1993 episode, along with another hit-and-run case, Jacquelyn Tendall.
Thoughts? This case has never aired on America's Most Wanted to the best of my knowledge but it is being placed in the Unsolved on TV section since, as noted above, it has aired on Unsolved Mysteries.
