The former police officer charged with murder and manslaughter of Justine Damond in Minneapolis pleaded not guilty to three charges on Friday.
Mohamed Noor did not speak during the 30-minute pre-trial hearing on Friday morning, with the plea entered by his attorney.
Noor has been charged with 2nd-degree intentional murder, 3rd degree murder and manslaughter over the July 2017 killing of the 40-year-old Damond in the Fulton neighborhood of Minneapolis.
Damond had called police to report a possible sexual assault behind her house, with Noor and his partner, Officer Matthew Harrity, responding to the call.
The pair reported being startled by a loud noise, shortly before Damond approached their squad car, at which point Noor opened fire.
FOX 9 reports that at Friday's hearing, Judge Kathryn Quaintance ruled that prosecutors would not be able to use any evidence of Noor's previous "bad acts" as a cop, which included him pulling a gun on a motorist after a minor traffic infraction.
They also won't be able to use the psychological evaluation he gave during a pre-hire screening with the MPD either. It revealed that Noor reported "disliking people and being around them" and was "likely to be asocial and socially introverted."
The judge also ruled that the fact Noor hasn't spoken to investigators about the shooting since it happened can also not be used against him, KSTP reports, as his attorneys argued he had the constitutional right not to make any self-incriminating statements.
