Myrtle Ann Green Hudson, 34, vanished from her Port Arthur, Texas, home on September 11, 1986. Her husband returned that day to find an apparent break-in, the couple’s 3-month-old daughter asleep and their 18-year-old daughter Willette bound and strangled in the attic. Myrtle herself was missing and her purse and keys were left behind.

Investigators treated Myrtle as a victim of foul play. In 2008, DNA evidence linked convicted violent offender Tommy Lee Stewart to the crime; Stewart later confessed to killing both Willette and Myrtle and said he left Myrtle’s body on Pleasure Island. Myrtle’s remains have never been recovered, and she is still listed as missing.

Anyone who knew Myrtle, her routines, or who was in Port Arthur around September 11, 1986, is asked to come forward with information that might explain what happened to her.
