Maria Guadalupe Barrientos, 43, was last seen June 6, 1994, in Sugarland, Texas. She left her job as a nanny that evening and did not return home; family reported her missing five days later. Her daughter and son-in-law initially said Maria left after an argument, but investigators found bloodstains in Maria’s car when it was recovered abandoned in Houston on June 30 and also located blood at her home, prompting suspicion of foul play.

In 2001 Maria’s son-in-law Frank Trejos confessed to killing her during an argument and implicated his wife, Brenda Barrientos, Maria’s daughter. Both led authorities to a field where they said they had buried Maria, but her remains were never recovered. Despite the lack of a body, both were convicted of murder in 2005. The case remains open with the Sugarland Police Department and unresolved because Maria’s body has not been found.

Did anyone in Sugarland or Houston at the time have information about Maria’s movements in June 1994 or about a vehicle abandoned in the city?
