The family of a woman killed when a New Jersey Transit commuter train slammed into a station this year has filed notice of their intent to sue.

Lawyers for Fabiola Bittar de Kroon's family filed a claim for damages Tuesday. It's the first step in the legal process of filing a lawsuit in New Jersey.

The 34-year-old Brazilian-born lawyer was standing on a platform when she was killed by falling debris in the Sept. 29 crash in Hoboken. It occurred just minutes after she had dropped off her 2-year-old daughter at day care.

More than 100 people were injured in the accident. It was later revealed that the engineer suffered from sleep apnea.

An NJ Transit spokeswoman said the agency usually does not comment on pending litigation.
