LINCOLN, Neb. (AP) — Police in Nebraska say a passenger’s cellphone automatically alerted responders after a car hit a tree in a crash that killed all six of its young occupants.

Five men in the car died at the scene of the crash in Lincoln in the wee hours of Sunday.

A woman died later at a hospital.

The victims ranged in age from 21 to 24.

Police are still investigating the cause of the crash.

But they say it was reported by an iPhone that detected the impact and called responders automatically when the phone’s owner didn’t respond.
