A shooting at Florida State University (FSU) on Thursday left two people dead and at least six others injured, prompting a large-scale law enforcement response and a campus-wide lockdown.

The suspected gunman, identified by Leon County law enforcement leaders as 20-year-old student Phoenix Ikner, was shot by police and taken into custody, according to university and law enforcement officials.

“Today, we experienced a tragic and senseless act of violence at the heart of our campus, FSU President Richard McCullough said. “At lunchtime, an active shooter opened fire at the Student Union. Two were killed. Six others were injured. We are heartbroken. We are grieving with the families, friends, and loved ones of those who were lost. We are holding close those who are injured, and we are standing by everyone who is hurting.”

Ikner, a current FSU student, is the son of a longtime Leon County Sheriff’s deputy, according to the Associated Press. Authorities said he used his mother’s former service weapon—a handgun—in the shooting. Additional weapons, including a shotgun, were recovered at the scene.

During a press briefing, FSU Police Chief Jason Trumbower confirmed that the two deceased victims were not enrolled students. Six other individuals were transported to Tallahassee Memorial HealthCare for treatment, with one listed in critical condition, according to reporting from The Guardian.

Gov. Ron DeSantis issued a statement following the shooting, expressing condolences and praising law enforcement’s response.

“Casey and I stand in solidarity and are praying for the entire Florida State community,” DeSantis said. “We’re mourning the two individuals who lost their lives in this tragic attack, and we wish well those who are currently recovering in the hospital. This killer must and will be brought to justice to the fullest extent of the law. I want to also thank the law enforcement personnel who were on the scene, both for the university as well as for the City of Tallahassee. They ran towards the danger. They stopped this killer from inflicting more harm, and there is no question that they saved lives. We are all Seminoles. Today we stand by to help in any way that we can.”

In a statement, Florida House Speaker Daniel Perez described the shooting as “every parent’s worst nightmare.”

“We are continuing to monitor the news here in Tallahassee and urge everyonWhat we are watching unfold at FSU is terrifying and every parent’s worst nightmare,” he said. “We are continuing to monitor the news here in Tallahassee and urge everyone to pray for the students, families, faculty, first responders and all involved.”

Following the incident, the university canceled all classes and events through Friday, April 18, and suspended all athletic competitions through the weekend. A university-wide shelter-in-place order was issued shortly after the first reports of gunfire and was lifted once the campus was secured.
