Diane Wilder, a 27-year-old Caucasian woman, was tragically murdered on January 11, 1979, in Bellingham, Washington. Diane, along with her friend Karen Mandic, was last seen alive when they went to check out a potential house-sitting job. The contact for this job was Kenneth Bianchi, who would later be identified as one of the infamous Hillside Stranglers. Bianchi, who had moved to Bellingham and found work as a security guard, lured the two women to their deaths.
Diane and Karen were raped and murdered, their bodies discovered in a wooded area. The investigation quickly focused on Bianchi due to his inconsistent answers and suspicious behavior.
Kenneth Bianchi, born on May 22, 1951, in Rochester, New York, had a troubled past marked by mental health issues and a history of criminal behavior. He was adopted by Nicholas and Frances Bianchi and exhibited signs of compulsive lying and violent tantrums from a young age. Despite his above-average intelligence, Bianchi was an academic underachiever and had a quick temper. His desire for power and control over people led him to pursue a career in law enforcement, but he was unsuccessful in securing a position. Instead, he found work as a private-security guard, frequently changing jobs due to theft from his employers.
Bianchi's criminal activities escalated when he moved to Los Angeles in 1976 to live with his adoptive cousin, Angelo Buono Jr., who had a history of sexual violence. Together, they became known as the Hillside Stranglers, responsible for the murders of at least ten women in Los Angeles. Bianchi's involvement in the Bellingham murders led to his arrest on January 12, 1979. He confessed to the crimes and provided information about the serial killings in Los Angeles. To avoid the death penalty, Bianchi agreed to plead guilty to the two murders in Bellingham and five murders in Los Angeles, testifying against Buono. Bianchi received eight life sentences and is currently incarcerated at the Washington State Penitentiary in Walla Walla.
The case of Diane Wilder's murder is a chilling reminder of the dangers posed by individuals like Kenneth Bianchi. Her tragic death, along with that of Karen Mandic, brought an end to Bianchi's reign of terror and highlighted the importance of thorough investigations and collaboration between law enforcement agencies. The legacy of the Hillside Stranglers continues to be a dark chapter in the history of American crime, with the victims' stories serving as a somber reminder of the impact of such heinous acts.
