The San Bernardino County Coroner is trying to determine what caused a 50-year-old woman to collapse and die at a park in Rancho Cucamonga late Friday morning.
Authorities were called to Golden Oak Park shortly before 11:30 a.m. on a report of a female experiencing a medical emergency.
“Deputies arrived and located the victim lying on the ground, and she was not breathing,” the sheriff’s department said in a statement.
Paramedics provided medical treatment and rushed the woman to a local hospital, where she was pronounced dead.
Her name was not released. She was a resident of Ontario, the sheriff’s department said.
Anyone with information was urged to contact the Rancho Cucamonga Sheriff’s Station at (909) 477-2800.
Rancho Cucamonga and many other communities in California’s Inland Empire were under a heat advisory as temperatures climbed into the 90s Friday afternoon and were expected to hit triple digits over the weekend.
