CNN is saying they think it was a slap
"A recently revealed search warrant may explain the source of that startling sound: a slap."
At most this would have been a small sound to get attention to show she was there - hardly a loud startling sound to get out the gun I wouldn't think. Still bizarre story.
I'm confused why this came out after they got a "search warrant" and searched the area. How would they be able to tell a slap??
"Upon police arrival, a female 'slaps' the back of the patrol squad," the search warrant states, according to Minneapolis Public Radio. "After that, it is unknown to BCA agents what exactly happened, but the female became deceased in the alley."
Um...
