Police say a 20-year-old driver struck and killed an 89-year-old woman because she was too busy looking through Facebook pictures on her phone to pay attention to the road.

Abby E. Sletten was charged with negligent homicide this week after a crash that killed 89-year-old Phyllis Gordon. According to reports, Sletten was driving around 85 miles an hour when she slammed into a car that had slowed to make an unauthorized U-turn. Gordon, who was sitting in the passenger seat, died at the scene.

Other motorists reported Sletten's brake lights never flashed.

According to the Star Tribune:

A search of Sletten's cellphone by police "determined that [she] was viewing pictures on her Facebook application … at the time of the crash," the criminal complaint read. "Sletten had also sent and received several text messages since she departed from Fargo."

She reportedly told police officers she couldn't remember the accident.
