During the fall of 1975, police investigators approached Elizabeth Kendall for whatever information she was able to give about Ted. They believed Elizabeth would most likely hold the key to Bundy's whereabouts, habits and personality. What investigators learned would later help link Ted Bundy to the murder victims.
On September 16th, 1975, Elizabeth was called into the King County Police Major Crime Unit building in Washington State and interviewed by Detectives Jerry Thompson, Dennis Couch and Ira Beal. She was visibly stressed and nervous, but willing to offer the police any information necessary to help the case. When asked about Ted, she stated that on the nights of the murders, she could not account for him. Elizabeth also told police that he would often sleep during the day and go out at night, exactly where she didn't know. She said that his interest in sex had waned during the last year. When he did show interest, he pressured her into bondage. When she told Bundy that she no longer wanted to participate in his bondage fantasies, he was very upset with her.
In a later interview with Elizabeth, investigators learned that Ted had plaster of Paris to make casts in his room, which she had noticed when they first began dating. She also noticed on a later occasion that in his car, Ted had a hatchet. But there was something else important to the case that Elizabeth would remember. She recalled that Ted had visited Lake Sammamish Park in July, where he had supposedly gone water skiing. A week after Ted had gone to Lake Sammamish Park, Janice Ott and Denise Naslund were reported missing.
After long hours of interviews with Elizabeth, investigators decided to shift their focus to Ted's former girlfriend in California. When police contacted her, she told them of how he had abruptly changed his manner towards her from loving and affectionate to cruel and insensitive. Upon further questioning, police learned that Bundy's relationship with his California girlfriend had overlapped with his relationship with Elizabeth and neither of them knew of the other woman. Ted seemed to be living a double life, filled with lies and betrayal. There was more to Ted than what investigators had initially expected.
Further investigation yielded more evidence that would later link him to other victims. Lynda Ann Healy was linked to Bundy through a cousin of his; more eyewitnesses would recognize him from Lake Sammamish Park during the time Ott and Naslund disappeared; an old friend of Bundy's came forward saying he had seen pantyhose in the glove compartment of his car; plus Ted had spent a lot of time in the Taylor Mountains where the bodies of victims had been found. Bundy's credibility was further dented when police discovered he purchased gas on credit cards in the towns where some of the victims had disappeared. Furthermore, a friend had seen him with his arm in a cast when there was no record of him ever having a broken arm. The evidence against Ted Bundy was building up, yet he still continued to profess his innocence.
