The attorney for 23-year-old Darreon Parker-Bell entered a not guilty plea on his behalf.

Parker-Bell faces charges of attempted first degree intentional homicide and first degree recklessly endangering safety. 

A search warrant report says the shooting was in retaliation for the in-custody death of Keishon Thomas, who died at District 5 days prior.

According to a criminal complaint, Parker-Bell indicated he intended to enter the police station armed with a gun, and once inside, he became angry when he could not receive any information about Thomas' death.

Parker-Bell fled the police station on foot after the shooting, and MPD officers shot him after he allegedly brandished a firearm toward them and refused to follow commands to drop the weapon. 

He was taken to an area hospital for treatment. 

Parker-Bell is due back in court May 26.
