A Texas national guard soldier has shot and wounded a migrant in the shoulder along the US-Mexico border.

According to Texas military records reviewed by the Military Times and the Texas Tribune, the soldier fired at the migrant on 15 January as he was attempting to detain the migrant.

The shooting is believed to be the first time that a national guard member deployed to the border as part of Texas’s border security mission Operation Lone Star has shot and injured a migrant.

The incident occurred west of McAllen, Texas, at around 4.20am when two national guard soldiers and border patrol agents tracked several migrants to an abandoned house.

Records reviewed by the Military Times and the Texas Tribune showed that upon the two soldiers entering the house, three of the migrants surrendered. A fourth migrant tried to escape from a window and one of the soldiers attempted to apprehend the migrant.

The migrant was reported to have wrestled with the soldier and struck him with his fists and elbows. At one point, the soldier drew his M17 pistol, fired once and shot the migrant.

Military records reviewed by the outlets does not indicate that the migrant had fired any weapons towards the soldier. It remains unclear whether the soldier intended to fire his gun.

The soldier has been identified as specialist Angel Gallegos. Gallegos shot the migrant in his left shoulder who was then transported to McAllen Medical Center for evaluation and treatment, the outlets reported. The migrant’s injuries are not life-threatening.

According to a federal law enforcement source who spoke to CNN, the migrant was from El Salvador.

“Customs and bBorder protection’s office of professional responsibility is reviewing the incident,” US Customs and Border Protection spokesperson Rod Kise told CNN.
