According to WSBTV.com in Atlanta, defensive attorney McCoy will represent McCoy, who has not been charged or even mentioned by authorities as a suspect.
Samuel, who defended former Baltimore Ravens linebacker Ray Lewis during his 2000 murder trial in Atlanta, said he is "getting up to speed" on the case and added that he will be speaking with the Milton Police Department.
McCoy's former girlfriend, Delicia Cordon was bruised and bloodied in what Milton Police called a "targeted" home invasion early Tuesday morning.
A friend of Cordon's accused McCoy on social media of being responsible, even though he was in South Florida training at the time of the incident.
McCoy has denied any involvement, while the Bills and the NFL have said they are investigating the situation.
