LOS ANGELES - A 74-year-old cyclist died of natural causes while riding a bicycle on Highway 39 above Azusa July 28.
Initially, the California Highway Patrol reported a collision with a vehicle resulted in the death of Stephen Naftilan. The Los Angeles County Department of Medical Examiner-Coroner revealed he died from acute cardian dysfunction.
Naftilan crashed while cycling at 10 a.m. at mile marker 24.10.
In a follow-up inquiry, Rodrigo Jimenez of the CHP Baldwin Park Office reported Naftilan "was unable to keep his bicycle upright and the right side of Mr. Doe's bicycle crashed into the asphalt roadway. A passerby and another bicyclist who observed the crash, responded to Mr. Doe and observed he was unresponsive."
CPR was administered until Los Angeles County Firefighters arrived. CPR was continued until Naftilan was pronounced dead at 10:52 a.m.
Highway 39 from East Fork Road to Roxspring Way was closed until 5:43 p.m. for the investigation. Alcohol and drugs are not considered factors in Naftilan's death, Jimenez said.
