Questions Surround JonBenet Suspect

Haney also said Karr delivered two of his children at home.

He transferred to the University of North Alabama in Florence. In early 2000, Karr was in his final semester, doing a teaching internship at the Kilby Lab School, when questions were raised about his classroom performance. He left without a degree or a teaching license, said Bill Jarnigan, director of university relations.

In July 2000, Karr moved with his family to Petaluma, Calif. A few months later, he got two permits to work as a substitute teacher and as an elementary teacher in Napa Valley Unified School District. For a few months, he worked at several schools in Napa and Sonoma counties until April, when the schools terminated him after reports he had been arrested.

On April 13, 2001, the Sonoma County Sheriff's Department charged him with five misdemeanor counts of possessing child pornography. Karr was jailed at first but released in October under a "supervised own recognizance" program, according to Roy Rochelle, the county's deputy chief probation officer.

Under conditions of his release from jail, Karr was ordered to stay away from "parks, schools, day care centers, swimming pools, beaches, theaters, arcades or other places where children congregate." He was barred from using computers and working in jobs dealing with minors.

Before his trial the following January, he disappeared. An arrest warrant was issued for violation of his release.

The school systems, alerted to the charges, terminated him.

In July 2001, after nearly 12 years of marriage, Lara Karr filed a divorce petition. Once her husband was released from jail, she filed for a restraining order to keep him away from her and their sons.

Although he was not violent, wrote his wife, a programmer for a mortgage company, Karr was controlling, forcing her to sever ties to family and friends. She said he had intentionally gotten her pregnant at 16 so he could marry her without parental consent under Georgia laws. "As a 16-year-old bride, I didn't know any better than to give in to his demands," Lara Karr wrote.
