Mail carrier found dead inside postal truck died from overheating, coroner says

The death of a 63-year-old U.S. Postal Service carrier who was found inside her truck amid soaring temperatures in Woodland Hills has been ruled accidental, the result of hyperthermia and other health-related conditions, the Los Angeles County coroner's office reported.

Peggy Frank of North Hills was found unresponsive on the afternoon of July 6 in the 4800 block of Calderon Road and was pronounced dead at the scene.

Temperatures hit a record 117 degrees in the area on the day Frank died.

The coroner's office listed her primary cause of death as hyperthermia -- above normal body temperature -- and obesity and idiopathic cardiomyopathy, or heart disease, as "other significant conditions.''
