Carlos Humberto Gonzalez was 43 when he was last seen on May 1, 1993, in Waco, Texas. He is 5 feet 7 inches and about 140 pounds. Carlos had post-traumatic stress disorder and required regular care, a factor that led authorities to classify him as endangered.

He has a distinctive U.S. Marine Corps tattoo on his left shoulder and may have had facial hair such as a mustache, beard, or goatee. Few details are available about the circumstances of his disappearance and no new leads have been reported; the case remains open with the Texas Department of Public Safety and the Laredo Police Department involved.

If anyone has information about where Carlos might be or recalls seeing him around May 1993, please contact the investigating agencies.
