Suspended Deerfield Beach commissioner Sylvia Poitier, 76, was found guilty on all four counts of falsifying official records.
The trial last less than three days and jurors deliberated for less than 90 minutes. Gov. Rick Scott suspended Poitier in April after she was arrested on five misdemeanor charges, one of which was dismissed prior to start of her trial.
Her Attorney Johnny McCray, Jr. said he might appeal the verdict. Poitier now faces a maximum of $4,000 in fines and four years in prison.
