(CNN)A transgender woman who traveled to the United States in a migrant caravan through Mexico has died while in the custody of immigration officials.
Roxana Hernandez, 33, of Honduras died Friday at a hospital in Albuquerque, New Mexico. She died from what appeared to be cardiac arrest, according to US Immigration and Customs Enforcement officials.
Hernandez was one of roughly 25 transgender and gender nonconforming individuals who joined the Central American migrant caravan in April.
She arrived at the San Ysidro, California, port of entry near San Diego on May 9 to seek asylum, according to ICE and Pueblo Sin Fronteras, which organized and guided the caravan.
She had been in custody for about two weeks, waiting to be deported, when she died.
Several immigrant advocacy groups claim Hernandez died due to medical negligence by immigration officials.
