Plea Deal In Fla. Teacher Sex Case

(CBS/AP)  A female teacher pleaded guilty Tuesday to having sex with a 14-year-old student, avoiding prison as part of a plea agreement.

Debra Lafave, 25, whose sensational case made tabloid headlines, will serve three years of house arrest and seven years' probation. She pleaded guilty to two counts of lewd and lascivious battery.

The former Greco Middle School reading teacher apologized during the hearing, saying "I accept full responsibility for my actions."

The boy told investigators the two had sex in a classroom at the Greco school, located in Temple Terrace near Tampa, in her Riverview town house and once in a vehicle while his 15-year-old cousin drove them around Marion County.

The boy told investigators Lafave told him her marriage was in trouble and that she was aroused by the fact that having sex with him was not allowed. He said he and Lafave, a newlywed at the time, got to know each other on their way back from a class trip to SeaWorld Orlando in May 2004.

If convicted at trial, she could have faced up to 15 years in prison on each count. The plea agreement also was designed to resolve similar charges pending in Marion County.

Hillsborough Circuit Judge Wayne Timmerman said LaFave also will forever lose her teaching certificate, must register with the state as a sexual predator, may not have any contact with children including the victim, and will not be allowed to profit from the sale of her story or personal appearances.

Prosecutor Michael Sinacore said the young victim's family wanted to get the case over with because of the intense public and media scrutiny.

"We're happy that the victim's family can put this case behind them," he said. "The whole process has been very difficult, and we hope they can now resume their lives."

After Tuesday's hearing, her attorney, John Fitzgibbons, said the plea was "a fair resolution of this case." Asked how she felt afterward, Lafave said "tired."

Fitzgibbons said in July that plea negotiations had broken off because prosecutors insisted on prison time, which he said would be too dangerous for someone as attractive as Lafave. He said then that she planned to plead insanity at trial, claiming emotional stress kept her from knowing right from wrong.

In August, Lafave's ex-husband, Owen Lafave,

with co-anchor Julie Chen on The Early Show, along with Dr. Julia Hislop, a clinical psychologist and author of the book "Female Sex Offenders."

Lafave said his ex-wife had never told him why she (allegedly) did it "and that's one of the hardest things that I've had to go through, is that I've never received a reason why."

He said "hindsight is 20-20. I can look back now and see some things that were peculiar about her behavior. But I had no idea anything like this was going on."
