Man charged with supplying chemicals in California fertility clinic bombing has died in custody, officials say

Daniel Jongyon Park, the man accused of providing chemicals for an explosive device used in the bombing of a California fertility clinic, has died while in custody at the Metropolitan Detention Center (MDC) in Los Angeles. According to a statement from the Federal Bureau of Prisons, Park was found unresponsive on a Tuesday morning around 7:30 a.m. Emergency medical personnel responded promptly, but he was later declared dead by hospital staff. The circumstances surrounding his death have not been disclosed, and an investigation is likely to follow to determine the cause.

Park had been arrested earlier this month at John F. Kennedy International Airport in New York, upon his return from Poland. He was charged with shipping a total of 270 pounds of ammonium nitrate to Guy Bartkus, who is believed to have carried out the bombing at the American Reproductive Centers in Palm Springs, California, on May 17. Prosecutors indicated that Park had sent 180 pounds of the explosive material to Bartkus, followed by an additional 90 pounds just days before the attack. The case highlighted concerns regarding domestic terrorism and the use of commercial chemicals for violent acts. As this is a developing story, further updates are expected as authorities continue their investigations into both Park's role in the bombing and the circumstances of his death.
