Three people were killed in a shooting at a Delaware courthouse that authorities say stemmed from a years-long custody dispute.
The New Castle County Courthouse remains closed Tuesday as workers repair shattered glass and investigators continued to probe Monday's shooting, which happened just as the courthouse opened for the day.
Authorities have not identified the gunman.
Wilmington Mayor Dennis Williams says one of the women killed was the shooter's estranged wife, but Delaware State Police Sgt. Paul Shavack would not confirm that Monday.
Bill Heriot says he was waiting to enter the courthouse when he saw a man pull out a pistol and fire at two women.
Heriot says the shooter then exchanged gunfire with police before falling to the floor.
