A 19-year-old former student was armed with an AR-15-style rifle and more than 600 rounds of ammunition when he opened fire at a high school in St. Louis, Missouri, Monday morning, killing two and injuring several others. according to the authorities.
The suspect, who was also killed during a shootout at Central Visual and Performing Arts High School, was identified by police as Orlando Harris, who graduated from the high school last year.
Harris, who had no criminal record, left a handwritten note in his car about his desire to “carry out this school shooting,” said St. Louis Michael Sack at a press conference on Tuesday.
Sack said Harris wrote, “I have no friends, no family, never had a girlfriend, never had a social life.” Sack said Harris called himself an “isolated loner,” who was a “perfect storm for a mass shooter.”
Authorities said Monday that there is “suspicion that there may be some mental illness that he was suffering from.”
The two slain victims have been identified by the school district as student Alexandria Bell, 15, and physical education teacher Jean Kuczka, 61.
Seven other victims, all aged 15 or 16, were injured and hospitalized. All were in stable condition, according to St. Louis.
Sack said Harris had seven rounds of ammunition in a chest pad and eight rounds of ammunition in a duffel bag.
“This does not include the number of magazines he left spilled on the stairs of the corridors along the way,” he added.
The shooting was reported around 9:10 a.m. local time, police said.
Authorities did not say how the gunman entered the building, but police stressed that the doors to the school were locked. On Tuesday, an official said he did not enter the school for a check.
Seven security guards were at the school, according to the superintendent of the St. Louis Kelvin Adams. Officials said security staff identified the suspect’s efforts to enter the school and immediately notified other staff.
“This could have been a horrible scene, it wasn’t, by the grace of God,” Sack said Tuesday.
“It’s very easy to get guns,” Sack said at a news conference Monday. “I’ve said it before: the gun laws in Missouri [are] very wide … they can carry them openly on any street, and there’s really nothing we can do about it.”
The mayoress of St. Louis, Tishaura Jones, said she had visited the students when the school year started.
“They were bright-eyed, bushy-tailed. We laughed, we sang, we danced. And now to be here for such a devastating and traumatic situation breaks my heart,” he said. “I am heartbroken for these families who send their children to our schools hoping they will be safe. Our children should not have to experience this.”
White House Press Secretary Karine Jean-Pierre addressed the shooting at Monday’s press conference, saying, “We need additional steps to stop the scourge of gun violence.”
“Every day that the Senate does not send the assault weapons ban to the president’s desk, or waits to take … other common sense action, is a day too late for our families and communities affected by gun violence,” he told reporters.
At Tuesday’s press conference, Sack encouraged anyone to notify police if “they are aware of an individual who appears to be suffering from some type of mental illness or distress” and is talking about buying weapons or causing harm.
