Maria Socorro Kimbrell, 28, was last seen June 19, 1991, in Huntsville, Texas. She was living with her husband, James Kimbrell, and studying criminology at Sam Houston State University. James told family she had left that day for a research trip to Honduras with a friend, but there is no evidence she ever reached that destination and all of her personal belongings — clothes, credit cards, toiletries — and her car were left behind.

Three weeks after Maria vanished, James informed her family about the supposed trip. Maria had a young son and routinely said goodbye before trips, which makes her disappearance without notice unusual. Soon after she went missing, James moved with their son, cut off phones and credit cards, and discouraged others from mentioning Maria. Rumors have linked her disappearance to political activism in Belize, where she supported opposition parties, but no evidence has surfaced to support that theory. James, who died in 1998, was never officially named a suspect.

Anyone who knew Maria, her movements in June 1991, or the people she planned to travel with is asked to come forward with information.
