Three days after former Roseville teacher Kelly Spaich pleaded no contest to unlawful sex with a 16-year-old former student, her husband has confirmed he's the one who turned her in to police last March.

"I did the right thing," said Jon Spaich, in an exclusive interview with News10. "She preyed on that child, I believe, and she walks around like nothing has ever happened and has shown no remorse whatsoever."

"(There's) not only one victim, like a 16-year-old boy, but there was (sic) plenty of others: our daughter, the boy's family, my family and myself," said Spaich, 29. The couple, now going through a divorce, has a 13-month-old daughter.

On Tuesday, Kelly Spaich, 28, pleaded no contest to a felony of unlawful sex with a minor. She was sentenced to four months in jail but the judge declared her eligible for alternative sentencing, which could include home detention with electronic monitoring. She was also put on four years probation and ordered to serve 400 hours of community service.

She will not be required to register as a sex offender.
