Hidalgo County Sheriff Lupe Trevino confirms an inmate died this week.
Trevino tells Action 4 the man died at the hospital and a preliminary report indicates his death was due to a self-inflicted trauma due to alcohol withdrawal.
Sources say the man ran head-first into a wall after having drug withdrawals, but Trevino said the cause of death has not been finalized because the death is an open investigation.
Authorities believe no foul play was involved.Investigators are analyzing evidence and consulting with a pathologist about the legal and medical aspects of the investigation.
The department has notified the Texas Jail Commission and the Texas Attorney General TMs Office, which is required by law.
Once the investigation is completed it will be handed to the District Attorney TMs office for review.
