It was right after the fifth-period bell last October that Sebastian Montano lay face down in the grass outside Alamogordo High School, screaming for his mother, as two police officers pinned him to the ground and thrust a Taser in his back. Moments earlier, a staff member had called police after learning that the 16-year-old, a special needs student who’d recently dropped out, was now trespassing on school grounds. A shy teenager with light brown hair and big green eyes, Sebastian was well known to staff and students at Alamogordo High. He had a long and messy school history, including 16 documented run-ins with school police officers — all in relation to behaviors associated with his disabilities: autism spectrum disorder, bipolar disorder, anxiety disorder, PTSD, epilepsy, and ADHD. But he was also a boy who showed great promise.
