San Antonio man sentenced to life in prison for fatal shooting in Atascosa County

ATASCOSA COUNTY, Texas – A San Antonio man was sentenced to life in prison Monday in an Atascosa County courtroom for a deadly 2023 shooting.

The same jury that decided the fate of defendant David Castleberry found him guilty within 20 minutes on Friday.

Castleberry was on trial in connection with the shooting of Lucio Carmona of San Antonio.

According to Atascosa County Sheriff David Soward, Castleberry and another defendant, Clarissa Guillen, knew Carmona and likely shot him during a robbery in early January 2023. The victim’s body was found on the side of a road north of Pleasanton in Atascosa County.

Investigators spoke with the victim’s family and learned he was last seen with the suspects the same day his body was discovered.

Castleberry and Guillen were arrested following a traffic stop in a stolen vehicle.

Soward said they confessed to their involvement in the fatal shooting and were charged with murder.

Guillen is awaiting trial in connection with the case.
