John Morgan, an attorney for the victims, told website Deadspin.com that the incident occurred on February 27, MyFoxBoston.com reports.
According to Morgan, the altercation began when a friend of Meriweather's allegedly beat up a woman in an Orlando-area bar. The situation soon escalated when the group moved to a house party, where Meriweather's friend reportedly was involved in a fight with the woman's brother.
At that time, Meriweather reportedly took out his gun and fired at the brother, with one bullet grazing his face and another hitting a man in the head. Both men survived the shooting.
Florida detectives have not yet made any arrests or commented on the investigation.
