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.

Daniel Park, 32, was arrested earlier this month after he was extradited from Poland, where he fled to four days after the attack.

Daniel Park, the suspect arrested in connection to the bombing at a fertility clinic in Palm Springs, California on May 17, met a horrific end in jail Tuesday morning.
