One of the shooters in the deadly STEM School attack in Highlands Ranch last month says he planned to target classmates who made fun of his gender identity.
16-year-old Alec McKinney was born female, but identifies as male.
The second suspect, 18-year-old Devon Erickson, also told police that McKinney led the attack.
Both teens told police they broke into a gun safe at McKinneys’ parents’ home then hid the weapons inside a guitar case and a backpack.
Both are charged with several counts including murder and attempted murder.
