A medical examiner has ruled the Jan. 3 death of Geraldo Lunas Campos, a detainee in U.S. Immigration and Customs Enforcement (ICE) custody in Texas, as a homicide, according to a recording obtained by news outlets. ICE initially reported that staff observed Campos “in distress” prior to his death at the detention center.

Details surrounding the circumstances of Campos’s death remain limited. ICE stated in its initial announcement that it is cooperating with authorities investigating the incident. The agency did not provide further specifics regarding the nature of the distress observed by staff, nor the cause of death beyond the initial observation.

The recording, which has not been independently verified by this news organization, reportedly contains statements from medical personnel suggesting a more serious cause of death than initially indicated by ICE. The medical examiner’s determination of homicide underscores the need for a thorough and transparent investigation into the events leading up to Campos’s death. Further information is expected as the investigation progresses. ICE has faced scrutiny in the past regarding the treatment and care of detainees in its facilities, and this incident is likely to renew those concerns. The location of the Texas detention center has not been explicitly released by ICE, further limiting public access to details surrounding the case.
