police have commented that they believe the serial killer may have "wined & dined" these girls...gotten comfortable with them...maybe saw them on more than one occassion.
I think that's certainly possible with regard to Gilbert. Perhaps this was Brewer's first time with her & things went awry from the start.
Hi, MrsPC, I've never been with a prostitute, but I assume that all johns want to have some kind of "good time" with sex workers and many of them might rehire them, but that is not an incriminating circumstance.
If one would believe the speculation here, Brewer was already a killer at the time of Shannan's disappearance. If, as you say (and it seems likely) that things went awry from the start, he would have been a dimwit beyond dimwits to kill her after a 21- or 23-minute 911 call and two encounters with her driver. And one assumes that he would also realize that her driver would be searching for her too.
A postscript: I just the read the article on Melissa Barthelemy that you kindly linked. To me, this adds one further indication that it is unlikely that Brewer is the serial killer: Barthelemy's last trick apparently didn't encourage third parties:
"Terry, who law-enforcement sources say was Barthelemy's pimp, said
she was very secretive about her plans that night and declined an offer for a ride. "This time she said no," said Terry, who denies that he was her pimp...."
and
"Police soon suspected the slayings were the work of an active serial killer. There is also some suggestion that some of the women veered from their usual routines when they fell prey to the murderer.
Three of the women seem to have left on their dates alone, and both Barthelemy and Costello appear to have been enticed by the promise of big money the nights they disappeared."
Since Barthelemy's disappearance occurred in 2007, well before Gilbert's, it seems unlikely that her killer would abandon procedures that worked so effectively in his earlier ghoulish job.
