Source: Medics from the Kings Mountain Fire Department tended to a 50-year-old man who suffered a heart attack on the scene and died after crashing his bicycle in the 2000 block of Kings Mountain Road around 12:30 p.m. Sunday, July 1, a San Mateo County Sheriff's Office spokesman told the Almanac. The Sheriff's Office does not have an incident report and thus does not have the victim's identity, place of residence or other details of the accident, including whether he was wearing a helmet, Lt. Larry Schumaker said. Jim Sullivan, fire chief of the Kings Mountain department, would not provide details on the victim's identity, citing victim privacy laws, but said the man's bike was not significantly damaged. Two 911 calls from cyclists who happened on to the scene alerted the San Mateo County dispatch center, which called the Kings Mountain medics and an AMR ambulance to the accident, Chief Sullivan said. In the phone calls, the victim was said to be conscious and breathing, "not completely alert" and "bleeding extensively," deputies said. While medics were treating the man, he went into "full arrest" and was declared dead at Stanford Hospital, deputies said. Sullivan said he could not verify that the man's death was a result of the accident.
