A retired New York City police officer who worked at Ground Zero after the Sept. 11 terrorist attacks and was later diagnosed with fibromyalgia is entitled to receive enhanced retirement benefits, an appellate court ruled Tuesday.

Writing in Sheldon v. Kelly, 101210/13, a panel of the Appellate Division, First Department, unanimously reversed Manhattan Supreme Court Justice Paul Wooten's 2013 denial of retired police officer's Annmarie Sheldon's petition to challenge the board of trustees for the Police Pension Fund's determination that Sheldon was not eligible for accidental disability retirement benefits.

Sheldon, a 41-year-old Long Island resident, was a police officer for 12 years before retiring in 2010. She will receive $2,500 more per month than the $3,500 in ordinary disability benefits.
