Forty-five years after her murder, Kathy Halle's family has received closure as police have definitively linked serial killer Bruce Lindahl to her death through DNA evidence. This technology was unavailable at the time of her death and has been instrumental in solving other cold cases, including the 1976 murder of Pamela Maurer and the 1982 murder of Debra Colliander. Lindahl died in 1981 but the evidence gathered from his exhumed body has now brought justice for Halle and her family, along with other victims. Lindahl's pattern of targeting women and girls in the western suburbs has also led authorities to suspect him in other unsolved cases, and they are using advancements in DNA technology to investigate those crimes.
