One week after the mass shooting, investigators are still working without solid descriptions of the shooter or gunmen who fired on the crowd.

The police are in the area of McLaren Street and Jackson Avenue. Officers are outside a house, standing outside, by the front and back door in a residential area.

After a shooting that wounded an officer, and the suspected gunmen, authorities in Superior offered further details of the incident.

Police found no victims at the scene, but later learned four men had taken themselves to a hospital for treatment of gunshot wounds.

The suspect charged in the deadly shooting of a man inside the MGM National Harbor casino in Maryland is being held without bail, Prince George's County State's Attorney Tara Jackson announced Friday.

Officials said there was a confrontation followed by an exchange of gunfire, leading to an officer shooting a 19-year-old, who died. It was unclear who shot first.
