Lucio Gustavo Carmona III, 24, was found dead on Tessman Road just north of Pleasanton, Texas, on January 3, 2023. An autopsy determined he died from a gunshot wound. Investigators identified 25-year-old David Castleberry and 21-year-old Clarissa Guillen, both of San Antonio, as primary suspects; the couple had recently met Carmona.

According to the investigation, Carmona had asked an acquaintance, Anthony Blue Arredondo, for a ride to cash a $1,400 check. When Arredondo could not help, he suggested Castleberry and Guillen. Surveillance footage shows Guillen making a drive-thru bank transaction with Castleberry in the passenger seat and Carmona in the back. After the transaction, Castleberry allegedly demanded the money at gunpoint, shot Carmona, and the couple later left the body on Tessman Road. Castleberry and Guillen were arrested in San Antonio on January 5, 2023, in a stolen vehicle and with outstanding warrants; both confessed and were charged with murder.

Castlebury’s trial and conviction came later; Carmona’s family remember him as a cherished member taken too soon. If anyone knew Carmona, his movements that day, or saw the vehicle involved, please share what can help the ongoing case.
