LAS VEGAS (AP) - Medical examiners in Las Vegas have determined that a 74-year-old swimmer whose body was found in Lake Mead died of natural causes.
An aide to Clark County Coroner Michael Murphy said Wednesday that an autopsy determined that Dwight Ernest Tarter of Boulder City died of conditions including an irregular heartbeat and hardened arteries.
National Park Service rangers and Boulder City police searched Monday for Tarter after he failed to return home from a swim in the Colorado River reservoir behind Hoover Dam.
Tarter's body was found Tuesday floating offshore near the Lake Mead Marina.
