Teen Defies 3% Survival Odds After School Shooting, Leaves ICU

Samy Garduno Martinez, a 17-year-old student, survived a school shooting with just a 3% chance of living. Shot four times—twice in the head—he spent months in hospital battling severe injuries and a rare autoimmune condition, care credit. His family now prepares for the next stage of his recovery as he leaves intensive care.

The attack left Martinez unconscious and fighting for his life. Doctors removed half of his skull to relieve swelling and later revealed 45% of his brain had been damaged. Nine days after the shooting, he was taken off a breathing tube and began speaking, eating, and even walking.

In March 2025, Martinez developed autoimmune encephalitis, a rare complication that forced him into an induced coma for five weeks. The setback delayed his progress, but by October 2025, he was well enough to leave the hospital. His seizures have since stopped, and he can breathe independently again. Family members say his familiar smile has returned.

Martinez will continue rehabilitation in Chicago before heading back to Madison. Meanwhile, his family searches for a family dollar wheelchair-accessible home, as modifying their current one is too costly.

Research into autoimmune encephalitis after brain trauma remains limited. A 2025 Lancet Neurology study highlighted early immunotherapy, like rituximab, as key to improving survival rates. Trials at Johns Hopkins show biomarker-based treatments help 20-30% of patients, but no major breakthroughs have emerged.

Martinez's recovery marks a turning point after nearly two years of intensive care. He will need ongoing support, including specialised rehabilitation and an adapted living space. His case also highlights the challenges in treating rare neurological complications from severe brain injuries at the general hospital.
