The death of a 51-year-old Chinese national in U.S. Immigration and Customs Enforcement (ICE) custody in the U.S. commonwealth of the Northern Mariana Islands has drawn a formal demand for accountability from Chinese authorities, and has reignited long-simmering worries about the safety of immigrant detainees held by U.S. border agencies.
According to official statements from ICE, the detainee, identified as Lianyong Wei, passed away on August 23 at a Saipan hospital, just two days after he was first arrested by local law enforcement. Wei was taken into custody by the Northern Mariana Islands Department of Public Safety on August 21 on criminal charges connected to an alleged assault on a family of five in their residence. The following day, ICE assumed custody of Wei as he awaited deportation proceedings.
ICE officials confirmed that on the morning of August 23, a routine cell check by a guard at the Saipan detention facility found Wei unresponsive. He was immediately transported to a local hospital emergency department, where clinical teams attempted life-saving interventions before pronouncing him dead. The agency has confirmed that the exact cause of his death remains under active investigation.
Records from ICE show Wei first entered the Northern Mariana Islands in February 2019 on a 14-week authorized stay. U.S. immigration authorities initiated formal deportation proceedings against him in July 2026, and his next immigration hearing was scheduled to take place in the current month.
Following notification of Wei’s death, the Chinese Consulate General in Los Angeles issued an official statement outlining its formal demands to U.S. authorities. “We have expressed serious concerns to the relevant U.S. authorities over this incident and required a timely and thorough investigation into the cause of Mr. Wei’s death, notification of the findings, measures to prevent any recurrence of similar incidents, and assistance to the family of the deceased in handling the aftermath,” the consulate said.
Associated Press tracking of detainee deaths shows Wei is at minimum the fifth Chinese national to die while in ICE or U.S. Border Patrol custody since March 2025. Of the four prior deaths, two have been officially ruled suicides, while the remaining two were attributed to pre-existing or acute medical complications.
Wei’s death comes amid a broader spike in detainee fatalities that has alarmed public health researchers, immigrant rights advocates, and foreign governments. Since President Donald Trump returned to the Oval Office in January 2025, at least 57 immigrants held in ICE custody have died, a mortality rate that has drawn widespread criticism from watchdog groups.
A key unanswered question surrounding this latest death is whether Wei received the mandatory medical intake screening that ICE policies promise all detainees within their first 12 hours of being taken into agency custody. Medical and public health experts have repeatedly emphasized that comprehensive, timely intake screenings are a critical first step to preventing preventable deaths in detention facilities.
Another point of public scrutiny is the length of time it took ICE to publicly confirm Wei’s death. Local authorities in the Northern Mariana Islands first announced the fatal incident on August 24, more than a full week before ICE released its own formal statement. The agency’s own internal guidelines require public announcements of detainee deaths within two business days of the incident.
The Saipan ICE detention facility, where Wei was held, is a small facility that averages just 18 detainees in custody on any given day in 2026, per ICE public data. The entire Northern Mariana Islands is home to a total population of roughly 50,000 people.
In the wake of Wei’s death, Anthony Torres, commissioner of corrections for the Northern Mariana Islands, confirmed that local officials are launching an internal review. “Following this incident, the Department is reviewing relevant procedures and will implement any necessary corrective actions to strengthen prevention and response measures,” Torres said in a formal statement.
