WILMINGTON, Del. (AP) — A Delaware State Police spokesman says 3 people have died in a shooting at the New Castle County Courthouse in Wilmington.

Sgt. Paul Shavack confirmed three people died in Monday's shooting in Wilmington. Earlier, the city's mayor said the suspected shooter was dead along with his wife.

Wilmington Mayor Dennis Williams said he was told the man shot and killed his wife and wounded two other people about 8:10 a.m. Monday. Williams says the couple was estranged.

Hours after the shooting, there was still a heavy police presence around the courthouse and streets were blocked off.

Dick Lawyer works across the street and said his office building had been on lockdown since about 8:15 a.m. He said he and colleagues were shaken at first but calmer hours later.
