HUDSPETH, Texas – The prison warden of a private Sierra Blanca detention center and his brother have been arrested in connection with a shooting that killed a migrant and injured another, according to a law enforcement source close to the investigation.

Mike Sheppard, the warden, and his brother Mark were incarcerated in the El Paso County Detention Center on Thursday.

Mike Sheppard was fired from the West Texas Detention Center due to an “out of order” incident, according to LaSalle Corrections.

ABC-7 spoke with Hudspeth County Sheriff Arvin West. He said he knew both men personally.

Sheriff West said he is still processing the shooting. He also said he was in shock when he learned the two men were involved.

West said these types of incidents don’t happen in the area.

He said the two men were from Florida and lived in Sierra Blanca. He said the brothers loved hunting. He said they hunted frequently in the area where the shooting took place.

Sheriff West also told ABC-7 that he was “staying away from the investigation.”

ABC-7 has contacted Homeland Security to verify the status of the other migrants in this group. We are waiting for an answer.

Authorities have confirmed that the remaining migrants are in custody.

On Tuesday, the DPS said the two men pulled up in a truck and shot at a group of “illegal immigrants” who were standing along the road to fetch water.

As ABC-7 reported Wednesday, Sierra Blanca Border Patrol agents were called in to assist the Hudspeth County Sheriff’s Office with the investigation related to the shooting.

According to the DPS, a migrant was shot and killed and a migrant was shot and is currently recovering at Del Sol Hospital in El Paso.

She is in stable condition.
