(CNN) Two Salvadorans -- a transgender woman and a man -- died in US custody near the Mexican border after suffering health problems in separate incidents this weekend, authorities said.

Jonathan Alberto "aka Johana" Medina Leon, 25, died at the Del Sol Medical Center in El Paso on Saturday, the Immigration and Customs Enforcement agency said.

Medina Leon first encountered immigration officials on April 11 "while illegally entering the United States from Mexico at the Paso Del Norte" Port of Entry, and was taken into ICE custody three days later.

ICE determined her fear of persecution if she were to be repatriated was credible on May 18 and she was issued a notice to appear before a US immigration judge on May 22.

On May 28, Medina Leon "requested to be tested for HIV and tested positive" and she was transferred to the hospital after she complained of chest pains.
