A 19-year-old graduate of St. Louis High School was shot and killed by police after the shooter left a post describing himself as a loner, it has been found.
Louis, Missouri police said on the 25th that they had found a note left by shooter Orlando Harris prior to the attack.
“I don’t have any friends or family, I’ve never had a girlfriend, I’ve never had a social life,” Harris wrote in the memo.
Police Chief Michael Sack said at a briefing, “It is possible that Harris may have had significant feelings of anger towards others living in healthy relationships.”
After graduating from an art high school in St. Louis last year, Harris went to his alma mater the day before and opened fire and was shot and killed in a confrontation with police.
Two people, a teacher in their 60s and a girl in their teens, were killed in the shooting, and seven students were injured.
Police said Harris was armed with an AR-15-style rifle and more than 600 rounds of bullets at the time of the shooting.
The AR-15 series rifle is a weapon that appears frequently in mass shootings in the United States.
In May 2022, 18-year-old Salverdore Ramos used the rifle in the shooting at Uvaldie Elementary School in Texas, which claimed the lives of 21 people.
