Five dead, including suspect, following Tulsa hospital shooting

Five people have died, including the suspect, following a shooting Wednesday at a Tulsa, Okla., medical center, police said.

Tulsa Police Department Deputy Chief Eric Dalgleish told reporters that officers were on the scene at 4:56 p.m. local time, within three minutes of receiving the call to the Natalie Medical Building at Saint Francis Hospital about a man armed with a rifle there.

By 5:01 p.m., officers made contact with the gunman and the victims on the second floor of the building, he said.

Four civilians are dead and police believe the alleged perpetrator died from a self-inflicted gunshot wound, authorities said. No officers were injured.

Dalgleish said the suspect is a "black male, estimated to be 35 to 40 years old" who had a rifle and a handgun on the scene. Police are still working to confirm the man's identity. 

An outpatient surgery center and a breast health center are located in the Natalie building.

The nearby Memorial High School is serving as a reunification site for family and friends.
