The death of an illegal immigrant inside a Texas detention camp is likely going to be ruled a homicide after a medical examiner determined his cause of death was asphyxia.

A fellow inmate claimed he witnessed Campos being choked to death by guards inside the facility, and a new report by The Washington Post states that allegation has now been supported by the medical examiner’s findings.

An employee from El Paso County’s Office of the Medical Examiner allegedly told Campos’s daughter that his death will likely be formally classified as a homicide.

Immigration and Customs Enforcement announced the death of detainee Gerald Lunas Campos on January 3 in a short statement claiming staff ‘observed him in distress.’
