Laquisha Jones, 30, was charged with felony elder abuse in December.
Witnesses said Jones pummeled Rodolfo Rodriguez with a brick. He suffered a shattered jaw and broken ribs.
Jones had a prior conviction for making criminal threats and had been on probation when she attacked Rodriguez.
Prosecutors said there was evidence in the case that showed it was a hate crime because Jones said "Go back to your country."
Jones had taken a plea deal last year during her trial.
