Shortly after midnight on January 4, 1974 (around the time that he terminated his relationship with Brooks), Bundy entered the basement apartment of 18-year-old Karen Sparks (identified as Joni Lenz, Mary Adams, and Terri Caldwell by various sources), a dancer and student at UW. After bludgeoning Sparks senseless with a metal rod from her bed frame, he sexually assaulted her with either the same rod, or a metal speculum, causing extensive internal injuries. She remained unconscious for 10 days, but survived with permanent physical and mental disabilities.
In the early morning hours of February 1, Bundy broke into the basement room of Lynda Ann Healy, a UW undergraduate who broadcast morning radio weather reports for skiers. He beat her unconscious, dressed her in blue jeans, a white blouse, and boots, and carried her away.
During the first half of 1974, female college students disappeared at the rate of about one per month. On March 12, Donna Gail Manson, a 19-year-old student at The Evergreen State College in Olympia, 60 miles (95 km) southwest of Seattle, left her dormitory to attend a jazz concert on campus but never arrived.
On April 17, Susan Elaine Rancourt disappeared while on her way to her dorm room after an evening advisors' meeting at Central Washington State College in Ellensburg, 110 miles (175 km) east-southeast of Seattle. Two female Central Washington students later came forward to report encounters—one on the night of Rancourt's disappearance, the other three nights earlier—with a man wearing an arm sling, asking for help carrying a load of books to his brown or tan Volkswagen Beetle.
The House Judiciary Committee opened impeachment hearings against the President on May 9, 1974, which were televised on the major TV networks. These hearings culminated in votes for impeachment.
In the early hours of June 11, UW student Georgann Hawkins vanished while walking down a brightly lit alley between her boyfriend's dormitory residence and her sorority house. The next morning, three Seattle homicide detectives and a criminalist combed the entire alleyway on their hands and knees, finding nothing. After Hawkins' disappearance was publicized, witnesses came forward to report seeing a man that night who was in an alley behind a nearby dormitory. He was on crutches with a leg cast and was struggling to carry a briefcase. One woman recalled that the man asked her to help him carry the case to his car, a light brown Volkswagen Beetle.
The Pacific Northwest murders culminated on July 14, with the broad daylight abductions of two women from a crowded beach at Lake Sammamish State Park in Issaquah, a suburb 20 miles (30 km) east of Seattle. Five female witnesses described an attractive young man wearing a white tennis outfit with his left arm in a sling, speaking with a light accent, perhaps Canadian or British. Introducing himself as "Ted," he asked their help in unloading a sailboat from his tan or bronze-colored Volkswagen Beetle. Four refused; one accompanied him as far as his car, saw that there was no sailboat, and fled. Three additional witnesses saw him approach Janice Anne Ott, 23, a probation caseworker at the King County Juvenile Court, with the sailboat story, and watched her leave the beach in his company. About four hours later, Denise Marie Naslund, a 19-year-old woman who was studying to become a computer programmer, left a picnic to go to the restroom and never returned. Bundy told both Stephen Michaud and William Hagmaier that Ott was still alive when he returned with Naslund—and that he forced one to watch as he murdered the other—but he later denied it in an interview with Lewis on the eve of his execution.
In light of his loss of political support and the near-certainty that he would be impeached and removed from office, Nixon resigned the presidency on August 9, 1974, after addressing the nation on television the previous evening.The resignation speech was delivered from the Oval Office and was carried live on radio and television. Nixon stated that he was resigning for the good of the country and asked the nation to support the new president.
A new string of homicides began the following month, including two that would remain undiscovered until Bundy confessed to them shortly before his execution. On September 2, Bundy raped and strangled a still-unidentified hitchhiker in Idaho, then either disposed of the remains immediately in a nearby river, or returned the next day to photograph and dismember the corpse.
On September 6, two grouse hunters stumbled across the skeletal remains of Ott and Naslund near a service road in Issaquah, 2 miles (3 km) east of Lake Sammamish State Park. An extra femur and several vertebrae found at the site were later identified by Bundy as Georgann Hawkins'.
The Ford White House considered a pardon of Nixon, even though it would be unpopular in the country. Nixon, contacted by Ford emissaries, was initially reluctant to accept the pardon, but then agreed to do so. Ford insisted on a statement of contrition, but Nixon felt he had not committed any crimes and should not have to issue such a document. Ford eventually agreed, and on September 8, 1974, he granted Nixon a "full, free, and absolute pardon", which ended any possibility of an indictment.
On October 18, Melissa Anne Smith—the 17-year-old daughter of the police chief of Midvale (another Salt Lake City suburb)—disappeared after leaving a pizza parlor. Her nude body was found in a nearby mountainous area nine days later. Postmortem examination indicated that she may have remained alive for up to seven days following her disappearance.
On October 31, Laura Ann Aime, also 17 years old girl, disappeared 25 miles (40 km) south in Lehi after leaving a café just after midnight. Her naked body was found by hikers 9 miles (14 km) to the northeast in American Fork Canyon on Thanksgiving Day.
In the late afternoon of November 8, Bundy approached 18-year-old telephone operator Carol DaRonch at Fashion Place Mall in Murray, less than a mile from the Midvale restaurant where Melissa Smith was last seen. He identified himself as "Officer Roseland" of the Murray Police Department and told DaRonch that someone had attempted to break into her car. He asked her to accompany him to the station to file a complaint. When DaRonch pointed out to Bundy that he was driving on a road that did not lead to the police station, he immediately pulled to the shoulder and attempted to handcuff her. During their struggle, he inadvertently fastened both handcuffs to the same wrist, and DaRonch was able to open the car door and escape.
Later that evening (8 November), Debra Jean Kent, a 17-year-old student at Viewmont High School in Bountiful, 20 miles (30 km) north of Murray, disappeared after leaving a theater production at the school to pick up her brother. The school's drama teacher and a student told police that "a stranger" had asked each of them to come out to the parking lot to identify a car. Another student later saw the same man pacing in the rear of the auditorium, and the drama teacher spotted him again shortly before the end of the play. Outside the auditorium, investigators found a key that unlocked the handcuffs removed from Carol DaRonch's wrist.
Legal disputes continued long after their break-up, and the dissolution was not formalised until 29 December 1974, when John Lennon signed the paperwork terminating the partnership while on vacation with his family at Walt Disney World Resort in Florida.
