Regarding the method of SS abduction
We need to take into account that it was the night of Australia Day. A lot of people out and about. Fireworks on The Swan in front of the city, big crowds at Kings Park and The City. A lot of people at pubs and clubs all over Perth.
SS had no knowledge that her taxi was 3-4 minutes away. Given the busy night right across the city it's not hard to imagine she was leaning on that bollard thinking "how long am I going to wait for this taxi? Will it be hours?". I know in the pre-smart technology era that sort of stuff was normal.
I also noticed people taking at face value friends and family saying "she wasn't than inebriated" and "she would never get in a car with a stranger" etc. I'm not saying she was quite drink, nor she necessarily got in a car with a stranger, nor she wasn't an intelligent and street wise woman BUT.......
Let's be realistic here. Young people do get trashed on alcohol. Young people do display risky behaviour. Even the best and most well-intentioned young adults do it.
The most likely scenario is as GreenDevil says because of the following reasons;
1. The car that didn't proceed through the lights. How can this be explained? It's possible the car turned into Chatsworth Tce, saw the news the next day and thought, "wow, that was me but if I say anything the police will no doubt search my property and I have a hydro set-up or kiddy-




etc so I will stay silent". But why has this person never come forward? Another option is the car turned down Chatsworth Tce to stay at a friends home, got up the next day, left the country because he/she is a foreigner. Possible but very unlikely.
2. It was Australia Day. SS had no idea how long a taxi would take and it's plausible that she was thinking she might have been in for a 1-2 hour wait. She had no reason to suspect anything untowards would happen because the CSK attacks hadn't started yet (as in widespread media coverage).
3. There was a car seen when CG was abducted who also never forward. That's 2 out of 3 abductions where a car was seen and neither occupants have come forward.
The other option is blitz attack. If we assume that the CSK also did Karra then he's adept at blitz attack abduction. He's able to get a girl without her making too much noise and without her seeing him. An ambush at a phone box is a great idea except how did he know a girl would call a taxi and then wait across the road? Surely a better spot is in the walk through at the set of offices right next to the phone box? It's possible he started there and crossed the road but if this were the case he would have grabbed her before crossed the road. If he was lying in wait near BC Body Club then he would have had to get her to the back of the Olifants building and walk along the Hwy which is very risky.
I think the evidence we have available strongly suggests the girls got into cars.
Which poses the question - why have the media been saying police think they were blitz attacked?
