4 killed in shooting at Tulsa medical building, shooter dead

A gunman carrying a rifle and a handgun killed four people Wednesday at a Tulsa medical building on a hospital campus, police said, the latest in a series of deadly mass shootings across the country in recent weeks.

Tulsa Police Department Deputy Chief Eric Dalgleish confirmed the number of dead and said the shooter also was dead, apparently from a self-inflicted gunshot wound.

The spate of recent gun violence across the country, including the killing of 19 children and two teachers at a Texas elementary school eight days ago by an 18-year-old gunman carrying an AR-style semi-automatic rifle, has led to Democratic leaders amplifying their calls for greater restrictions on guns, while Republicans are emphasizing more security at schools.

The divide mirrors a partisan split that has stymied action in Congress and many state capitols over how best to respond to a record-high number of gun-related deaths in the U.S.

It was unclear what prompted the deadly assault in Tulsa, Dalgleish said.

“It appears both weapons at one point or another were fired on the scene,” Dalgleish said. “The officers who arrived were hearing shots in the building, and that’s what led them to the second floor.”

Police responded to the call about three minutes after dispatchers received the report at 4:52 p.m. and made contact with the gunman roughly five minutes later, at 5:01 p.m. Dalgleish said.
