An attorney for the Gottis tells News 12 that the deal would have dismissed the charges for Gianni Gotti if her mother, Kimberly Gotti, pleaded guilty to a misdemeanor.
The mother and daughter were both charged with assault after they were said to have punched a woman in the face at a Locust Valley High School basketball game in February, prosecutors say.
However, the pair's defense attorney says his clients were not the aggressors.
The case will return to court on June 4.
