Authorities say a 19-year-old man has been charged in the fatal shootings of four men at or near a Chicago restaurant.

Police say Maurice Harris faces four counts of first-degree murder in connection with the March 30 slayings. Additional details are expected to be released at a Wednesday news conference.

Harris was arrested Tuesday and it wasn't immediately known whether he had a lawyer.

Two were found dead inside the restaurant, a third was found unresponsive outside and a fourth was found unresponsive a block away. They included two brothers whose mother worked at the restaurant.

The deaths were part of gun violence in a South Side Chicago neighborhood that left seven dead in a 12-hour period. Police Superintendent Eddie Johnson has said it was mostly due to gang conflict.
