Indian River County Sheriff's Office detectives began an investigation after a judge presiding over a domestic hearing injunction on behalf of Aaron Richardson discovered two marriage licenses -- one to Arkina Sneed in 2004 and Irene Clark last year.
Sneed told detectives she married Richardson in October 2010 at the county courthouse but didn't know he was still married to Clark. Sneed said she wouldn't have married him if she knew he was still married.
Detectives said they then interviewed Richardson, who denied ever being married to Clark.
According to the arrest warrant, Richardson said he was in prison being treated for a physiological problem and was taking medication for it. Richardson said he started dating Clark after he got out of prison, but he didn't remember getting married to her.
Clark told detectives she was aware that Richardson had married someone else.
