On October 28, 1993, Terry Knorr contacted America's Most Wanted, who asked her to contact detectives in Placer County, California (the county in which Suesan's body was found) who took her claims seriously and followed up with an investigation. The detectives linked the two Jane Does found in the area in 1984 and 1985 to Terry Knorr's detailed stories of her sisters' deaths and concluded that she was telling the truth. Knorr's son William was arrested on November 4, 1993 in Woodland, California where he had been living and working. Robert Knorr, Jr. was charged with his sisters' murders while he was serving a 16-year sentence in an Ely, Nevada prison for the 1991 murder of a Las Vegas bartender. On November 10, 1993, Theresa Knorr was arrested at her home in Salt Lake City. At the time of her arrest, Knorr was using her maiden name of "Cross" and was working as a caretaker for her landlord's 86-year-old mother.
