A shooting at a Tennessee private Christian grade school left three students and three adults dead, including the head of the school, Monday and the shooter was killed by police, authorities said. 

The victims were killed in the attack at the Covenant School, authorities said. Nashville police say officers engaged with and killed the shooter, identified as a 28-year-old female carrying two "assault-type rifles" and a handgun.

The shooter was identified as Audrey Elizabeth Hale, a Nashville resident, who identified as a transgender woman. Investigators were investigating a home connected to her. Nashville police Chief John Drake said Hale possibly prepared for the shooting, including having written a manifesto. 

"We have also determined that there were maps drawn of the school in detail of surveillance entry points. At one point she was a student at that school," he said. "There was a vehicle nearby that gave us a clue as to who she was."

Police say the shooter entered the building through a side door and fired shots before moving to the second floor, where Hale was confronted by responding officers. They don't believe she was wearing any body armor, authorities said.

A search of a Honda Fit driven by Hale to the school campus yielded "additional material," police said. Hale also allegedly fired at responding police vehicles from a second-story window.

Hale was armed with two AR-style weapons, including a rifle and pistol, and a handgun. Two of the weapons may have been purchased legally in the Nashville area, Drake said. Investigators were probing a possible theory for a motive but did not disclose any details. 

Officials at the medical center say three young students were transported to Monroe Carell Jr. Children’s Hospital at Vanderbilt with gunshot wounds. All three were pronounced dead after arrival. The three more adults were also pronounced dead following the attack. All three were staff at the school.

The victims were identified by police as Evelyn Dieckhaus, Hallie Scruggs, and William Kinney, all age 9, Cynthia Peak, 61, Katherine Koonce, 60, and 61-year-old Mike Hill. Koonce was the head of school at Covenant, according to the school's website. 

The Covenant School is a private Christian institution for students up to 6th grade, according to its website.

"My heart breaks with news of the school shooting at The Covenant School this morning," Rev. Mark Spalding of the Diocese of Nashville said in a statement. Let us pray for the victims, their families, and the Covenant Presbyterian community."
