Wondering if this serial killer's background could shed light on this one...

"Born at Pocahontas, Idaho, in 1940, Hansen was the son of a Danish immigrant who followed in his father's footsteps as a baker. In his youth, Hansen was skinny and painfully shy, afflicted with a stammer and a severe case of acne that left him permanently scarred. (In later years, he would recall his face as "one big pimple.") Shunned by the attractive girls in school, he grew up hating them and nursing fantasies of cruel revenge.
Hansen was married in 1961 and divorced within the year, following his first arrest, on charges of arson. Six years later, he wed another Pocahontas native and she followed him to Anchorage, Alaska, where he opened his own bakery and prospered in a new land, safely removed from the painful memories of childhood and adolescence. Hansen took flying lessons and purchased his own private plane, earning a reputation as an outdoors man and hunter who stalked Dahl sheep, wolves, and bear with a rifle or bow and arrow.
In 1972, Hansen was arrested twice more, charged with the abduction and attempted rape of a housewife (who escaped his clutches) and the rape of a prostitute (who did not). Serving less than six months on a reduced charge, he was picked up again, for shoplifting a chain saw, in 1976. Convicted of larceny, he was sentenced to five years in prison, but the verdict was overturned on appeal, the Alaska Supreme Court regarding his sentence as "too harsh."
Unknown to local authorities, Hansen's visible activities were only the tip of a very lethal iceberg. According to his subsequent confession, Hansen preyed consistently on women in the decade between 1973 and 1983, murdering 17 and raping another 30 who survived.
As targets, he selected prostitutes, "exotic" dancers and the like, abducting them by airplane to the wilderness outside of Anchorage, where they were forced to act out Hansen's private fantasies. "If they came across with what I wanted," he explained, "we'd come back to town. I'd tell them if they made any trouble for me, I had connections and would have them put in jail for being prostitutes." Resistance -- or demands for payment after sex -- resulted in assorted victims being murdered, sometimes with the ghoulish touch of Hansen stripping them and stalking them like animals, making the kill with a hunting knife or his favorite big-game rifle.
The first indication of a killer at large came in 1980, when construction workers unearthed a woman's remains near Eklutna Road. Stabbed to death in 1979, she was never identified, dubbed "Eklutna Annie" by police assigned to work the case. Later that year, the corpse of Joanna Messina was found in a gravel pit near Seward, and a special task force was organized to probe the killings. Topless dancer Sherry Morrow had been dead ten months when hunters found her body in a shallow grave beside the Knik River, but the discovery brought authorities no closer to a solution in their case.
In 1983, Hansen decided to save time and energy by bringing his victims home. He called it his "summer project," laying the groundwork by packing his wife and two children off on a European vacation."
