The mother of a 24-year-old man who was found dead inside a Rikers Island jail building has filed a $100 million claim notice alleging that Rikers staff for two days “disregarded and ignored” her son’s pleas for medical help.

The mother’s lawyer expects the litigation will involve broad civil rights issues and will include a wrongful-death claim, among numerous other causes of action, unless a settlement is first reached with New York City.
