Stephanie Shae Henderson, 21, vanished from her Levelland, Texas, home on November 28, 1993, after an argument with her husband, Ricky Don Henderson. She called her grandmother asking to be picked up, but was gone by the time her grandmother arrived. Ricky said friends from Hobbs, New Mexico, had picked her up, yet Stephanie’s purse and her only pair of shoes were left behind.

Weeks later Stephanie’s grandmother received a letter supposedly from Stephanie, postmarked in Lubbock and saying Stephanie was living in Hobbs. Police later tested the envelope and found the DNA belonged to a male, a finding that heightened suspicions of foul play. Stephanie’s body has never been found, and authorities consider the circumstances suspicious.

The investigation remains open and law enforcement is seeking new leads. If anyone knew Stephanie, her movements in late November 1993, or has information about the people she was said to be with, please come forward.
