DA: Music teacher solicited child sex, and it's not the first time

STOCKTON, Calif. -- A music teacher in north-central California is facing charges after police say he tried to meet with an underage girl for sex -- and it's not the first time he was convicted for a child sex offense, CBS Sacramento reports.

Stockton police say 70-year Keyes Kelly had been talking to undercover officers for two months, after the vice unit posted ads on Craigslist posing as a 13-year-old girl.

The San Joaquin County District Attorney's Office says Kelly, a Stockton music professor, husband and grandfather responded to one of those ads.

The criminal complaint accuses Kelly of soliciting sex online from someone he believed was a 13-year-old girl. He allegedly set up a meeting with "her" at a Lowe's in Stockton, the station reported.

Prosecutors say instead of finding a teen, he found the Stockton Police Department.

"If the allegations are true, then good for the police department," said Kelly's neighbor, Mike Souza. "None of my children went there. But the parents of children who went there should speak to their children I would think."

The DA's office says Kelly has taught children for decades and has a prior conviction from three decades ago for lewd acts with a child. Kelly fought and had the conviction expunged from his record in 1989, when laws were more lax with misdemeanor sex offenses, CBS Sacramento reported.

"We have people out there who are lurking for and actively trying to persuade our children to have sex with them, and this sting operation is to stop that type of behavior," said deputy district attorney Elton Grau.
