Manhunt ends with arrest of suspect in deadly Delaware hospital shooting

The suspect in a fatal Delaware hospital shooting has been arrested in Philadelphia and is expected to be extradited, officials said.

The 23-year-old man is expected to face charges in the Wilmington Hospital shooting, the city of Wilmington said in a statement.

Authorities said the attack is believed to have been targeted and isolated. Officials have not released the names of the victims or the condition of a survivor who was shot.

Law enforcement sources told ABC News that preliminary information suggests the incident began when one hospital employee shot two co-workers.

Wilmington Police Chief Wilfredo Campos told a news conference Tuesday night that investigators were working to identify and locate the shooter and determine how they left the building.

Campos declined to release the identities of the victims or the condition of the survivor “out of respect for the families,” he said.

The shooting was reported around 3:30 p.m. at Wilmington Hospital, according to David Karas, chief administrative officer of the Wilmington Police Department.

ChristianaCare, which operates the hospital, said it diverted emergency patients and took steps to ensure safety for patients, staff and visitors. The hospital lockdown was lifted Tuesday night.

Wilmington Mayor John Carney said hospital workers and patients hid as officers cleared rooms during the search. “If ever there is a place that should be a sanctuary for such violence, that is the place,” he said.

Police believe the shooting was an isolated workplace incident.

At the news conference, John Carney acknowledged the victims and hospital workers who hid as law enforcement went from room to room, clearing the building.

“If ever there is a place that should be a sanctuary for such violence, that is the place,” Carney said.

The scene remains active as the investigation continues.

Violence has been a persistent problem at hospitals across the U.S.

Wilmington, which has about 71,000 residents and is Delaware's largest city, is about 25 miles (40 km) south of Philadelphia.
