(AP) — Authorities have arrested a sex offender in the death of an Iranian exchange student who was attending the University of Nebraska at Omaha when she was killed in 1983. Bud Leroy Christensen, 67, was awaiting extradition from Nebraska to the Pottawatomie County Jail in Council Bluffs, Iowa, on a first-degree murder charge, The Omaha World-Herald reported. During a court hearing Tuesday, he waived his right to fight extradition. Fishermen found the body of Firozeh Dehghanpour, who was in her mid-20s, on Aug. 14, 1983, under a bridge north of Council Bluffs. An autopsy determined she bled to death from several cuts.
