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

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)[5][6][7] 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.[9][10] 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.[11] His friend called a crisis hotline before contacting the Davidson County Sheriff's Office at 10:13.[12]

At 10:11, Hale shot through a set of glass side doors and entered the building.[13] He was armed with two rifles and a pistol.[14][15] At 10:13, police received a call about an active shooter.[16][17] 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.[18][19] A teacher told an officer that the students were in lockdown and two were missing.[20]

Officers entered the building at 10:25 and they searched each room for Hale. They heard gunshots coming from the second floor.[21] 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
