The cause of death of an inmate who died on April 27 at the Pitchess Detention Center North Facility in Castaic was released by Coroner’s officials on Wednesday.

Herman Charles Nash, 47, experienced a “sudden” cardiac episode which resulted in his death at the facility, said John Cades of the Los Angeles County Coroner’s Office.

According to Cades, Nash’s death was caused by a combination of two medical conditions: coronary artery thrombosis — more commonly called a heart attack — and cardiomegaly, the medical term for an enlarged heart.
