Nashville police fatally shot a school shooter on Monday after the suspect killed three students and three adult staff members at Covenant School, a private Christian school for students in preschool through sixth grade. 

The Metropolitan Nashville Police Department (MNPD) believes the 28-year-old shooter who identified as transgender was a former student but is still gathering information. 

“Two MNPD officers who entered the building and went to the sounds of gunfire engaged the shooter on the second floor and fatally shot her,” MNPD announced in a tweet.

Police received calls about the shooter Monday shortly after 10am. The six patients were taken to Monroe Carell Jr. Children’s Hospital and Vanderbilt University Medical Center, where they were pronounced dead on arrival, according to The Associated Press. 

Students who survived the attack were bused to Woodmont Baptist Church, where they could reunite with their parents. 

Nashville Mayor John Cooper tweeted his condolences to the families affected by the school shooting. 

“In a tragic morning, Nashville joined the dreaded, long list of communities to experience a school shooting,” Cooper said. “My heart goes out to the families of the victims. Our entire city stands with you. As facts continue to emerge, I thank our first responders and medical professionals.”
