Daniel Park had been charged in connection with the bombing outside a fertility clinic in Palm Springs, California. His cause of death wasn't immediately known.

Daniel Jongyon Park — a man federal authorities said provided chemicals to make explosives used to bomb a California fertility clinic in May — has died, according to a statement from the Federal Bureau of Prisons.

The man charged with supplying explosives used to bomb a California fertility clinic in May took his own life while in pretrial custody, the Los Angeles County medical examiner ruled in autopsy results made public on Thursday.
