On Wednesday, a Mexican asylum seeker died by suicide on a bridge across the Rio Grande after he was denied entry into the United States, Reuters reports.

The man, who has not been identified but is believed to be in his 30s, trekked the Pharr–Reynosa International Bridge, which connects Reynosa, Mexico and Pharr, Texas. 

According to officials, when the man was turned down by U.S. Border Patrol, he pulled out a knife and cut his throat. 

“He committed suicide,” one of the officials said. 

The man killed himself at 5 p.m. on Wednesday on the Mexican side of the bridge.

The news wire reports that the attorney general’s office for the Mexican state of Tamaulipas is investigating the man’s death.

The death comes three months after a Cuban asylum seeker who had spent five months in U.S. detention waiting for a court hearing on his case died of a suicide at a private prison in Louisiana.
