The man who allegedly shot and killed the assistant principal of a charter school in Chicago’s downtown Loop has not been criminally charged for the Thursday shooting since he was released by police.

       Abnerd Joseph, 32, an assistant principal at the downtown campus of Intrinsic Schools, was fatally shot Thursday around 7:30 p.m. in a hallway on the 48th floor of a building in the first block of East Monroe Street, which police listed as Joseph’s address.

       According to a police report obtained by the Tribune, the man who shot and killed Joseph has a license to own and conceal his possession of firearms. Joseph had been knocking on residents’ doors and “causing a disturbance” before the shooting, the report said.
