June 24 (UPI) -- Daniel Jongyon Park, the Washington state man charged with providing explosive materials to a suicide bomber who attacked a California fertility clinic last month, died Tuesday while in federal custody.
Park, 32, was found unresponsive inside his cell around 7:30 a.m. PDT, at the Metropolitan Detention Center in Los Angeles, where jail staff immediately began life-saving measures, the Bureau of Prisons announced in a statement. He was pronounced dead after being transported to a local hospital.
The Federal Bureau of Investigation and U.S. Marshals Service are investigating Park's death. No details have been released and a cause of death has not been determined.
Park, of Kent, Wash., was the alleged accomplice of Palm Springs bomber Guy Edward Bartkus, who detonated a vehicle bomb outside the American Reproductive Centers on May 17. Several people were injured and Bartkus was killed.
