Louis Longhi

An unemployed truck driver, Louis Longhi was sentenced to indefinite psychiatric confinement in Denmark on March 11, 1983, for the murder of Heike Freiheit, a West German female hitchhiker. He was 29 years old at the time of the murder.

Longhi was deported from Switzerland in 1977 after spending years in a mental institution. The night of the murder, Longhi invited Freiheit to his room where he washed her hair and, after she fell asleep, tied her up. He then repeatedly washed her hair, substituting salad dressing, honey and cottage cheese for shampoo when it ran out. He cut off her clothes and tugged the noose around her neck when she tried to call for help. She was killed by strangulation and Longhi hid the body in the wall of his room where it was discovered by workmen 9 months later. Longhi maintained that Freiheit's death was an accident.

Physicians observed that Longhi was a virgin with a "sexual obsession about women's hair", a fixation that began when he started stealing shampoo and wigs from hair salons at age 10. Eventually, he developed an obsession with washing women's hair. The Danish Court ruled that he was dangerous and should be "confined indefinitely."
