One hot summer night in south Minneapolis, three people went into an alley to make sure everything was safe.
Mohamed Noor, the cop on patrol with his partner. Justine Ruszczyk Damond, the worried neighbor who'd called 911 twice to report cries she'd heard in the dark.
She was on the phone with her out-of-town fiancé when the squad car pulled up behind her home.
"OK," she said, delivering the last words he'd ever hear her say. "The police are here."
Then she ran outside, barefoot and in her pajamas, where a startled Noor shot her dead, one month before her wedding day.
The trial of the Minneapolis police officer who killed the woman who called him for help is heading into its third week.
In a Hennepin County courtroom, the jury studied a collage of crime scene photos and videos, listened to Damond's voice on the phone with the 911 operator, and began the painful work of weighing evidence in a case that rips every raw nerve in the national debate over police shootings, court bias, race, immigration and press freedom.
The body cameras Noor and his partner carried didn't start rolling until it was too late. But police cameras toggled on and off throughout the night like a stop-motion horror film.
