A Mexican national has died while in the custody of Border Patrol in Texas Monday. The unidentified 45-year-old sought medical attention twice before his death and was diagnosed with cirrhosis of the liver and congestive heart failure, although the cause of death is still unknown. He is the third known migrant to die in recent months while in government custody. In December last year, two Guatemalan children died in the care of Border Patrol agents in New Mexico, sparking outrage and calls to overhaul the agency’s response to sick migrants.
