### Instruction:
Please give me a short bulleted list of what happened in the 2023 Covenant School shooting incident

### Input:
On March 27, 2023, a mass shooting occurred at The Covenant School, a private Presbyterian Church in America parochial school in the Green Hills neighborhood of Nashville, Tennessee. Local resident and former student of the school Aiden Hale (formerly Audrey Elizabeth Hale) killed three children and three adults. Hale, 28, was killed by two Metropolitan Nashville Police Department officers responding to the incident.

Hale was initially reported to be a woman and referred to by his birth name by police. Later, it was confirmed that Hale was a trans man who went by the name Aiden and used he/him pronouns.

Hale drove a Honda Fit to the school, arriving at 9:54 a.m. CDT and parking it in the lot. At 9:57, Hale sent an Instagram message to an old friend saying an earlier post he made was "basically a suicide note" and that he planned to die that day. His friend called a crisis hotline before contacting the Davidson County Sheriff's Office at 10:13.

At 10:11, Hale shot through a set of glass side doors and entered the building. He was armed with two rifles and a pistol. At 10:13, police received a call about an active shooter. He walked across the second floor of the school before opening fire. He fired into several classrooms; no one in the classrooms was injured because the teachers had fortified doors and sheltered the students. The police first arrived at the school at 10:24. A teacher told an officer that the students were in lockdown and two were missing.

Officers entered the building at 10:25 and they searched each room for Hale. They heard gunshots coming from the second floor. Five Metro Nashville police officers went upstairs and saw him in a lobby area, firing through a window at arriving police vehicles. Two of the officers fired four times each killing him at 10:27, 14 minutes after the initial 911 call was made

### Response:
