WACO (March 23, 2009)—Baylor University Student Jesus Zepeda, 22, has been charged with criminal solicitation of a minor after Austin police said he exchanged sometimes-explicit messages over a nearly two year period in an AOL chat room with what he thought was a 14-year-old girl.

The teenager was actually an undercover Austin Police Department investigator who maintained what an arrest warrant affidavit described as “a sporadic online relationship” from May 2007 until last month with an AOL user with the screen name “Final Cloud777.”

In September 2007, a subpoena was issued to AOL, which identified Zepeda as the account holder, the affidavit said.

On Feb. 3, according to the affidavit, Zepeda again contacted what he thought was the teenage girl, “communicated in a sexually explicit manner” and again asked, “if she could meet in person for sex.”

During the chat, three sexually explicit photographs were sent to the officer who was pretending to be an underage teenage girl, the affidavit said.

On March 17, Austin and Baylor police officers searched Zepeda’s dorm room and interviewed the student who, according to the affidavit, admitted to the sexually explicit online chats and to sending the explicit photos.

Zepeda was arrested on Friday.

He was released Saturday after posting a $10,000 bond.

He's from Ferris, a town of about 2,100 that straddles Dallas and Ellis Counties.
