Pilot dies alongside 3 nieces on wedding day in tragic Arizona helicopter crash

A helicopter crash in a remote Arizona canyon killed a local man and his three nieces on his wedding day after the aircraft apparently struck a slackline strung across the terrain, authorities said.

FOX 10 in Phoenix reported that the victims of the crash, which happened Friday, were identified by family members.

The crash happened near Superior in Pinal County, east of the Phoenix area, shortly after the helicopter took off from Pegasus Airpark. All four people on board were killed when the aircraft plunged to the canyon floor.
