An investigator says a Dallas police officer who shot and killed her neighbor after mistaking his apartment for her own said that when she inserted her key in his door, it opened because it had been slightly ajar.
David Armstrong of the Texas Rangers wrote in an arrest affidavit released Monday that Officer Amber Guyger said it was nearly completely dark inside the apartment when she entered it Thursday night and she thought she was encountering a burglar in her home.
He says Guyger said the person ignored her verbal commands and she fired twice. One struck Jean in the chest and he later died.
The affidavit says Guyger was on the phone with 911 reporting the shooting when she turned on the apartment lights and discovered she was in the wrong apartment. It says Jean's apartment was the one right above Guyger's and the apartment layouts and exterior hallways were nearly identical.
