Summary based on the NamUs case record (MP9123) and 6 other sources
Maria Guadalupe Barrientos, aged 43, was last seen on June 6, 1994, in Sugarland, Texas. She worked as a nanny and left her job that evening but never returned home. Maria’s daughter and son-in-law, who lived with her at the time, reported her missing five days later. Despite their claims that Maria had left home after an argument, suspicions arose when her car was found abandoned in Houston on June 30, with bloodstains inside the vehicle. A search of her home also uncovered bloodstains, leading investigators to suspect foul play.

In 2001, Maria's son-in-law, Frank Trejos, confessed to murdering her during an argument, with the assistance of his wife, Brenda, Maria's daughter. Although they both led authorities to a field where they claimed to have buried Maria, her remains were never found. Despite this, both were convicted of murder in 2005. The case remains classified as unresolved, as Maria's body has not been recovered.

The case is still open with the Sugarland Police Department, and they encourage anyone with information to come forward.
