Before Minneapolis police officer Mohamed Noor fatally shot Justine Damond, a woman had approached the back of the patrol car and "slapped" it, according to a court document filed Monday.
A search warrant was filed by Minnesota Bureau of Criminal Apprehension investigators to look at the area where the shooting happened and gather evidence as part of the investigation.
"Upon police arrival, a female 'slaps' the back of the patrol squad," according to the search warrant. "After that, it is unknown to BCA agents what exactly happened, but the female became deceased in the alley."
But the document doesn't explicitly say it was Damond who slapped the back of the police cruiser. It also doesn't say whether that was the loud noise that Noor's partner, Matthew Harrity, said he heard and was startled by before the shooting.
A BCA spokesperson declined to provide additional details to Minnesota Public Radio, citing the ongoing investigation.
