Possible bomb left by shooter

Oklahoma Highway Patrol and Muskogee Police Department officials are investigating a possible bomb at a Muskogee home that may be connected to the shooter.

A Muskogee police official said Tulsa police notified MPD that the shooter may have left a bomb at a residence in the 3300 block of Park Place North, according to Tulsa-based station KJRH.

Muskogee police evacuated the residence and asked people in the area to remain inside their homes.

The Highway Patrol’s bomb squad was called to the scene. A warrant is being obtained to search the home.

Back in Tulsa

Officers searched every room in the Natalie Building for potential threats. They were still working to clear the building as of 6:30 p.m.

Detectives and officers interviewed witnesses from throughout the building, especially the second floor, Dalgleish said.

Police closed down Yale Avenue in the area where the shooting occurred.

“Please stay away from the area and yield to all emergency vehicles as we deal with this response,” Tulsa Police Department Chief Wendell Franklin said on social medial.

‘Senseless act’

Cliff Robertson, President and CEO of Saint Francis Health System, spoke during the news conference, shaken by the four deaths.

“We are an organization that believes in the power of prayer, and there’s nothing more this community can do for us than to pray for the families and loved ones and the victims of this senseless act,” Robertson said. “There will obviously be many questions, and there will be a bumpy road ahead of us, but there are over 10,000 people that are part of the Saint Francis Health System that everyday commit their lives to people in need, and this senseless, horrible, incomprehensible act is not going to change that.”

Tulsa Mayor G.T. Bynum acknowledged the daily heroism and sacrifices of Saint Francis medical personnel.

“This campus is sacred ground to our community. This is where heroes come to work to save the lives of people within our community,” Bynum said.

Saint Francis administrators issued an official statement on Wednesday’s mass shooting. That statement is as follows:

“Saint Francis Health System is grieving the loss of four members of our family. As a faith based organization, the only recourse we have at this moment is to pray while we navigate this tragedy.

Out of respect for the families, we are not commenting on or releasing names of those lost or injured at this time.

We are sincerely thankful for the quick response by the Tulsa Police Department, first responders and EMS agencies. And, our deepest gratitude extends to the members of our own Saint Francis family who cared for their own during this incident.

To allow our staff and caregivers the opportunity to process today’s tragedy, all Warren Clinic appointments in Tulsa and Broken Arrow scheduled before noon tomorrow have been cancelled. Additionally, the Warren Clinic Orthopedic offices in the Natalie Building will be closed until further notice.

We ask that you please pray for the employees and physicians of the Saint Francis Health System.”
