Four people have been arrested in connection with a mass shooting in Leland, Mississippi, that left six dead and over a dozen injured during homecoming weekend.

Teviyon L. Powell, William Bryant, and Morgan Lattimore face capital murder charges, while Latoya A. Powell is charged with attempted murder, according to the FBI.

It is unclear whether the suspects have legal representation.

The FBI stated that additional arrests are possible and urged anyone with information to come forward, CBS News has reported.

The shooting, one of several deadly incidents in Mississippi that weekend, occurred shortly after a high school football game.
