After a car struck a tree early on Sunday in Nebraska, killing all six of its young occupants, a passenger’s cellphone immediately alerted emergency personnel, according to police.

Around 2:15 a.m., a car crash in Lincoln, about 3 miles east of the state Capitol, claimed the lives of five of the men who were in it. A 24-year-old lady who was transported to the hospital in a severe condition subsequently passed away there.

The 22-year-old driver was one of the five men who perished. One victim was 21 years old, one was 23 years old, and two others were 22 years old.

The crash’s exact reason was not disclosed by the police, but they did say that an iPhone reported it after it sensed the impact and immediately alerted emergency services when the owner didn’t answer.
