[2] Allison was credited by some sources with assisting a number of police investigations over the years, including the 1967–1968 search for a missing boy (later found drowned) in Nutley, New Jersey, the 1974 kidnapping of Patty Hearst, and the 1976 Son of Sam murders.
Two police detectives in Paterson, New Jersey, accused her of offering them money to say that she had been helpful in the 1979 search for a missing boy, later found murdered (Allison denied the charge).
[3][4] She was a frequent target of scientific skeptic James Randi,[4] who cited her failure in the Atlanta case when naming her for one of his earliest "Uri Awards" (later called the Pigasus Awards) in April 1981.
[6][7] In May 1988, she was featured on the television series Unsolved Mysteries and, later that year, Secrets of the Unknown.
A resident of Nutley, she died of heart failure on December 1, 1999, at Clara Maass Medical Center in Belleville, New Jersey.
