During the party, Brown consumed alcohol and became intoxicated, the lawsuit said. Brown left the party at 12:18 a.m. still intoxicated, according to the lawsuit. Then, around 12:30 a.m., she was driving and struck 56-year-old Maria Schwab, who was on a sidewalk, the court document said.

The City of Chicago has been named as a defendant in a wrongful death lawsuit stemming from last December when an off-duty police officer, accused of driving drunk, fatally struck a pedestrian.

The officer herself, Tangie Brown, and the bar where she had been before the crash, were already named in the wrongful death lawsuit.
