Here's an article about it: (click).

The incident happened January 12, 2013, at Frederick, Maryland. Frederick as a small, quiet town that is maybe 50 miles northwest of Washington, DC. Mostly, what I remember about Frederick is that it has some great bookstores. I'd think I should feel safe dropping a 26-yr-old Down Syndrome man off at a theater in Frederick.

Ethan Saylor was 294 pounds and had Down Syndrome. He saw the movie "Zero Dark Thirty" and wanted to see it again, but didn't buy a second ticket. Officers ended up pulling him from his seat and restraining him with three pairs of handcuffs. His larynx was damaged, and that that and other factors led to his death by asphyxiation.

This 2016 Baltimore Sun article says that police in Maryland are now required to get training on how to handle people with disabilities, so maybe that's one good result of the fate of Ethan Saylor.
