More details:
"..Officer Amber Guyger told the authorities she was returning from a 15 hour shift when she had mistaken her neighbor's four floor apartment at South Side Flats, in Dallas, for her own home on the third floor on Thursday.
Entering the darkened apartment, the door to which she has since claimed was slightly ajar, she told police she mistook 26-year-old resident Botham Jean for a burglar and shot him in the chest. He was later transported to hospital where he was pronounced dead.
The affidavit says Guyger only realized she was in the wrong apartment during the 911 call when she turned on the light. It states that Guyger's apartment was directly below Jean's and the apartment layouts and exterior hallways were nearly identical.
Investigator David Armstrong of the Texas Rangers said Guyger gained access to her neighbor's apartment because, when she inserted her key in his door, it opened because it had been slightly ajar.
He says Guyger said the person ignored her verbal commands and she fired twice. One struck Jean in the chest and he later died.
Dallas Police Association President Mike Matas says that three different investigators told him to warn Guyger to stay away from her apartment for her own safety, Fox 4 Dallas reports..."
