THE FBI is appealing for help to find a Sydney man critical to investigations into a notorious American serial killer jailed for 223 years.
US authorities believe David Parker Ray - dubbed the ''Toy Box Killer'' after the name he gave his home-made torture chamber - abducted, sexually assaulted and killed as many as 40 women.
Ray boasted about the murders but police have not found the bodies and, after his death in 2002, now fear many of his crimes will go unsolved. The FBI needs to contact a Sydney man known only as Mark, who wrote a letter to a possible victim of Ray named Connie, who was abducted in 1995.
The FBI sought the help of the Australian Federal Police but local leads went nowhere.
A spokesman for the FBI, Frank Fisher, told The Sun-Herald someone in Australia might be able to shed light on the matter. ''We suspect the Connie whom Mark wrote to could be the same Connie who was possibly abducted by David Parker Ray because Mark's letter was found in Ray's possessions.''
He said the Australian man had lived in London, Canada and, in June 1990, was living on Old South Head Road in Bellevue Hill, Sydney. ''He worked in Sydney around 1990 in a hospital for people with developmental disabilities, and for the AIDS Council of NSW. He jogged with Gay Frontrunners around June 1990.''
Anyone with information is asked to call Crime Stoppers on 1800 333 000.
