According to authorities, there has been a shooting incident at Rose State College in Oklahoma that resulted in the death of one person and the arrest of another.

The campus, located in Midwest City, was briefly locked down and an active-shooter protocol was implemented. This comes only a few weeks after students and staff had practiced what to do in the event of a shooting.

“We are currently experiencing an active shooter situation on campus,” the school tweeted at 12:36 p.m. local time on Monday. “Please shelter in place and follow instructions from law enforcement officials. More information to follow as it becomes available.”

About an hour after the shooting, the campus was declared safe and students were asked to leave, while all activities and classes were cancelled. The school also advised people to avoid the area south of Humanities and Administration Building. Police did not disclose the identity of the victim or the suspect.

According to a witness, Kevin McCormack, he heard gunshots and saw one man falling to the ground, another man holding a gun, and a woman attempting to pacify him.

“Almost immediately, we said, ‘Go, go, go!’ and took off,” McCormack told the Associated Press.

Police praised everyone who had been on hand for their quick response.

“Things got locked down real quick,” Midwest City Police Chief Sid Porter told reporters. “I just think they did a fantastic job listening to the school and everybody staying down and not panicking because we didn’t know what was going on.”

According to Porter, the two men had a connection through a domestic situation, but he did not disclose the nature of their relationship or the motive for the shooting.

It is also unclear whether either the victim or the suspect were affiliated with the school as either staff or students. The victim was shot once before the campus police intervened and apprehended the suspect.

“They ordered him to drop the gun, which he did, and they took him into custody,” Porter said.

Crime scene tape was erected around the college’s humanities building, and multiple law enforcement agencies were investigating

The 13,000-student campus located 8 miles east of Oklahoma City canceled classes for Monday and Tuesday following the shooting. The school is also providing counseling options for those impacted by the incident.

Fortunately, no other injuries were reported, and the college expressed appreciation to the first responders in a message posted later on Monday.

“Our top priority at this time is the well-being of our students, faculty and staff,” the school said. “We understand that this event has been deeply distressing for our community, and we are currently working to coordinate counseling services for those in need. We all be alerting our students, faculty and staff as soon as these services become available.”
