If the person happens to be a street worker AND aboriginal like Darrylyn Ugle who was murdered, then the case is most likely sitting on the bottom of the pile. I can hardly find any information about her or what happened to her. List goes on doesn't it.
I think Darrylyn Ugle's murder (whose decomposing body was found in a burnt-out tree stump at Farrell Grove near Mundaring Weir in April 2003) is significant in terms of links to other unsolved cases of murdered sex workers in Perth during the 1990's and early 2000's. However, I'm less inclined to believe these cases are linked in anyway whatsoever with the CSK and do believe that it is the work of a second, unidentified (?) serial rapist. I think there is certainly suspicions on behalf of WAPOL regarding who exactly that person is (as discussed below) but perhaps the physical evidence is few and far between. These were not cases that hit the radar like the Claremont abductions.
It was confirmed in 2004 that a 49 year-old abbatoir worker from Perth's northern suburbs (who was charged with the attempted murder of a 22 year-old prostitute in December 2003) was also being investigated for possible links to the murder of Darrylyn Ugle and was the same man also being investigated in regard to the disappearance of Sarah McMahon. I believe that on the basis of the conclusions made at the inquest into Sarah McMahon's disappearance, this previously unidentified man may be a reference to Donald Victor Morey who IMO has every potential to be linked to more on the W.A missing list.

IMO it is the Mundaring Weir site that is significant and key in any discussion involving Morey. It is the location where the prostitute (who Morey is currently serving time for attempting to murder) was taken and it is also the chosen dump site for Darrylyn. Curiously, although Morey technically lived in Marangaroo, he also owned a house with his de facto in Chidlow . . . a direct route to Mundaring Weir.
Whether the Mundaring Weir location is in fact the unknown location Estelle Blackburn discusses in her article (16 June 2007; Sunday Times Special Report titled "Serial Kill Fears" )where she publicly raised suspicion her violent ex was involved in the Claremont murders (or other murders) has also crossed my mind as being something worthy of noting on the basis of the description of the chosen site in correlation with the timeline of missing /murdered persons.
Quote from article:
"A later girlfriend told me that once he had bound and gagged her and put her in his boot, releasing her later in bush with water nearby. While assaulting and abusing her, he threatened to kill her and said, pointing to the water that there was ``another blonde ***** down there''."
