LAS VEGAS (AP) - A 59-year-old man died Saturday while competing in the swimming leg of a triathlon in southern Nevada.
The Clark County Coroner's Office says Patrick Hayden was pronounced dead at 9:30 a.m. at Boulder City Hospital.
The former principal at Arbor View High School in the Las Vegas area was found unconscious in Lake Mead by an event kayak patroller, who alerted park rangers of an unresponsive swimmer. Efforts to revive him failed.
Hayden's sister, Dawn Hayden, told the Las Vegas Review-Journal (http://bit.ly/19ZqHMy ) that he was a dedicated family man who was participating in the Pumpkinman triathlon with two of his sons.
She says plans called for Hayden to compete in the swimming leg of the triathlon and for his sons to perform the biking and running portions.
Lake Mead National Recreation Area spokeswoman Christie Vanover says park rangers are unsure what caused him to lose consciousness in the water.
The coroner's office is scheduled to perform an autopsy Sunday to pinpoint the cause of death.
Dawn Hayden says her brother was an active swimmer who frequented a pool to stay in shape.
He was principal of the high school from 2005 until his retirement in 2011. He previously coached many sports, including tennis and baseball.
