SANTA ROSA, California —  Prosecutors said they would wait to pursue child pornography charges from five years ago pending against the suspect in the JonBenet Ramsey case.

John Mark Karr, 41, worked briefly as a substitute teacher in Sonoma County, California, until early 2001, when he was charged with possessing child pornography. He was jailed for about six months, then disappeared before his trial was due to begin in January 2002.

Karr is scheduled to be flown Sunday to Boulder, Colorado, to face charges of first-degree murder, kidnapping and child sexual assault in connection with the 1996 slaying of the child beauty queen.

Sonoma County District Attorney Stephan Passalacqua said Friday that the misdemeanor child pornography case will wait while Colorado authorities to pursue the Ramsey case.

"The priority is the homicide case," Passalacqua said. But, he added, "if for some reason that doesn't materialize, then we'll revisit the issue and make an appropriate decision at the time."

With good behavior and credit for time already served, Karr probably would not spend much more time in jail if convicted, but it would require him to register as a sex offender, Passalacqua said.
