Neighbors of a white cop who shot dead a black man in Dallas on Thursday night after walking into his apartment have disputed her claim that his door was ajar when she arrived at it. 

Seconds before Amber Guyger, 30, shot Botham Jean in the chest, one neighbor said they heard a woman in the hallway knocking on a door and yelling: 'Let me in, let me in.' 

Another neighbor then heard gunshots and afterwards claimed to have heard a man shouting: 'Oh my God. Why did you do that?'  

The witness told Jean's family's lawyer Lee Merritt they think those were his last words. Jean's mother Allison said she believes there is more to her son's death than has been revealed.
