• Daniel Park, 32, was found unresponsive at the Metropolitan Detention Center in Los Angeles on June 24 and was pronounced dead after being taken to a hospital, the Bureau of Prisons said.
• Park was accused of supplying about 180 pounds of ammonium nitrate to Guy Edward Bartkus, who used the chemicals to construct a car bomb that devastated the American Reproductive Centers clinic.
• Guy Edward Bartkus died in the May 17 blast outside the Palm Springs fertility center, an attack that caused major property damage and injured four people.
