Federal authorities charged a Sweetwater man with extortion for sending Snapchats to a woman as he used the alias of a University of Tennessee football player.

Brandon Douglas Shanahan, 22, is charged with intent to extort money and other things from a woman through Snapchat while using the name “Camsutton2323.” He's accused of threatening to injure her reputation.

Shanahan pleaded not guilty to the charges on Wednesday, and was released on bond.

The woman believed she was communicating with Cameron Sutton, a senior cornerback who wears the No. 23 at UT.

A law enforcement investigation revealed Sutton was a victim of criminal impersonation.

Authorities in a released statement noted that Sutton had not actually conversed with the woman via Snapchat or other means, and was not aware that Shanahan impersonated him.

Documents reveal that the victim said Shanahan told her she sent him nude photos on Snapchat while she was drunk. The victim couldn't remember whether that was true.

The following day, the victim said Shanahan told her he would post the purported nude photos unless she sent more photos.

The investigation indicates Shanahan may have contacted a number of other women.

The FBI asks anyone who thinks they were a victim of extortion by Shanahan through his Snapchat name “Camsutton2323” to call (865)544-0751.

If convicted, Shanahan faces a maximum of two years in prison.

The investigation is ongoing.
