A man was killed and four other people wounded in a mass shooting in Aurora early Sunday morning, according to Aurora police. The shooting happened just after 4 a.m. in the parking lot of a strip mall at 12455 East Mississippi Avenue at a gathering that was “related to a Juneteenth celebration,” police said in a statement. A very large crowd had gathered at the strip mall for a Juneteenth party inside a unit in the mall, according to police. “At some point earlier in the evening the presumed organizers of the celebration began denying access to the unit,” police said in a statement.
