Plot Synopsis

20/20 ON ID INVESTIGATES is a two-hour series that more thoroughly explores content previously airing on 20/20. Each documentary takes a look at these cases through a modern lens, challenges original perceptions and sheds new light on each story.

The first installment, "Ted Bundy," premiered on Saturday, March 30, 2019 from 9-11pm ET/PT on Investigation Discovery, and repurposes content from the two-hour 20/20 special episode about Ted Bundy that debuted on Friday, February 15, 2019 from 9-11pm on ABC. Ted Bundy and his horrifying killing spree in the 1970s have captured the nation's attention for decades. On the heels of the 30th anniversary of Bundy's execution, this two-hour program provides new insight into Bundy's vicious past and crimes. He admitted to murdering at least 30 women and girls, many of whom he kidnapped and sexually assaulted. Authorities believe he may have been responsible for as many as 100 homicides. The prime-time documentary features new interviews with key players, including surviving victims and those who were vital in helping place Bundy behind bars. The program features footage from the ABC News archives and interviews with former FBI Special Agent Bill Hagmaier, who interviewed Bundy on death row for over 200 hours; Ray Crew, one of the first Florida State University police officers to arrive at the Chi Omega crime scene; Ken Katsaris, former sheriff of Leon County, Florida, who helped connect Bundy to THE CHI Omega murders; Kathleen McChesney, former Washington State detective who worked on the Bundy case; Robert Keppel, former detective who took Bundy's detailed confession about the murder of Georgeann Hawkins; Larry Simpson, lead Florida prosecutor who put Bundy behind bars; John Henry Browne, one of Bundy's defense attorneys; Kathy Kleiner, Karen Chandler and Cheryl Thomas, surviving Bundy victims; and Joe Berlinger, director of the upcoming film "Extremely Wicked, Shockingly Evil and Vile," starring Zac Efron, and executive producer and director of the Netflix documentary "Conversations with a Killer: The Ted Bundy Tapes."

On the outside, Bundy appeared to be a charismatic young man with a promising future. He graduated from the University of Washington with a degree in psychology, had a girlfriend and a strong interest in politics, and was accepted into law school. Meanwhile, Bundy was living a double life and had an evil side, initially only visible to his victims. He preyed on young women, often attacking, murdering and sexually assaulting them.

Bundy's first conviction was for kidnapping Carol DaRonch in Utah. In the meantime, police in Utah, Washington and Colorado were starting to connect Bundy to a number of disappearances and murders, and he was eventually charged with the murder of Caryn Campbell. While awaiting trial in Colorado, he escaped twice. The first time he jumped out the window of a courthouse library and the second time he climbed through the ceiling of his jail cell. After his second escape, Bundy fled to Florida, where he murdered two women at Florida State University's Chi Omega sorority house and savagely beat three others. A few weeks later, he kidnapped and murdered 12-year-old Kimberly Leach, in what was his last killing. After he was caught by chance during a traffic stop, Bundy was arrested and had two separate murder trials. He was convicted of murdering Chi Omega sorority sisters Margaret Bowman and Lisa Levy, and of kidnapping and murdering Leach. He was sentenced to death; and days before his execution, he confessed to at least 30 murders. Bundy was executed in the electric chair at Florida State Prison on Jan. 24, 1989, for the murder of Leach.
