'The 17-year-old had been arrested back in 2021 for possession of a ghost gun and a high capacity magazine.
His arrest came when he was a student at Overland High School and some fellow students reported photos on social media showing Lyle with a gun, the sources said.
A search of the teenager’s home then uncovered the ghost gun and magazine. He was later expelled from the school and began attending East High School.
As part of a school safety plan based on his prior behaviour, Lyle was required to be patted down for weapons each day on arrival at East High, Denver Police Chief Ron Thomas said at a press conference on Wednesday.
The bloodshed came three years after the Denver school board voted to eliminate its program of assigning armed city police officers, known as school resources officers, to its public school campuses, relying instead on the school district's own security team.'
