Authorities say a Tucson man has died after parachuting from a cell phone tower at night and hitting high-voltage power lines.

Pinal County sheriff's Lt. Tamatha Villar says 23-year-old Darrell Dunafon and two friends broke into a cell tower site about 30 miles south of Phoenix on Friday night and were parachuting off the approximately 400-foot-tall antennae.

Dunafon's parachute became tangled in nearby 12,000-volt power lines and he was shocked with a live wire.

Villar says the two friends called for help, and rescue crews turned off the power and cut Dunafon down. He had a slight pulse but was pronounced dead at a hospital in the nearby town of Casa Grande.

Dunafon was a Tucson resident who recently moved to the southeast Phoenix suburb of Queen Creek.
