Motions to block testimony on a prior sex crime conviction and for a new interview of the victim in the trial of a Salt Lake man charged with aggravated sexual abuse of a child were argued in 2nd District Court.

David R. Krogh, 40, of 3666 S. Caroline St., is scheduled for trial April 6 on the charge, a first-degree felony, stemming from incidents from January to April 1986 in Centerville.Defense attorney Wally Bugden and prosecutor Brian Namba Tuesday argued three motions filed by Bugden, seeking to block testimony about Krogh's 1978 conviction on forcible sodomy. They also requested a new interview by a psychologist of the defense's choosing and to block testimony about Krogh's flight from Utah and eventual arrest in California.

Krogh, according to court records, was sentenced in 1978 to one-15 years in the state prison on a forcible sodomy conviction. That prior conviction elevated his current charge to aggravated sexual abuse of a child, a first-degree felony that carries a prison term of five years to life and a minimum mandatory sentence of five, 10, or 15 years.

Judge Douglas L Cornaby has already granted Bugden's motion to separate the trial into two phases. The first will hear evidence on the sexual abuse charge. If Krogh is found guilty, a second hearing will be set to present evidence on his prior conviction.
