Police are searching the former Huntingdale home of the man charged with the Claremont serial killer murders of Jane Rimmer and Ciara Glennon.
Bradley Robert Edwards lived at the home in Fountain Way between 1991 to 1997 - during the years in which he is accused of carrying out the Claremont killings.
It's understood he lived at the home at the time he allegedly abducted and raped a 17-year-old girl at Karrakatta Cemetery in 1995.
Nine reporter Renae Henry said police searched the home extensively at the time of Mr Edwards' arrests.
