From the article:
"Despite his setback in California, Israel continued to expand on the East Coast—and to generate controversy. In 1985, Vincent Milletich, an autistic 22-year-old, suffered a seizure and died after he was put in restraints and forced to wear a white-noise helmet. Five years later, 19-year-old Linda Cornelison, who had the mental capacity of a toddler, refused to eat. On the bus to school, she clutched her stomach; someone had to carry her inside, and she spent the day on a couch in a classroom. Linda could not speak, and the staff treated her actions as misbehaviors. Between 3:52 p.m. and 8 p.m., staffers punished her with 13 spatula spankings, 29 finger pinches, 14 muscle squeezes, and 5 forced inhalings of ammonia. It turned out that Linda had a perforated stomach. She died on the operating table at 1:45 a.m.
The local district attorney's office examined the circumstances of Vincent's death but declined to file any charges. In Linda's case, the Massachusetts Department of Mental Retardation investigated and found that while Linda's treatment had "violated the most basic codes and standards of decency and humane treatment," there was insufficient evidence to prove that the use of aversives had caused her death."
