I remember, that LE said, the girls were murdered a very short time after they met BG and that BG left the location/crime scene very late at around 4pm. MOO Most of us were shocked, that he dared to leave the crime scene as late as that, and we were thinking of all the things, he could have done to the girls. MOO The time, SC had seen the dirty man/BG, perhaps was the reason for LE's timeline. We wondered, why they would know, when BG was done with his crime and left the area. MOO
MOO for no link.
PS: Now we still wonder, how LE knew, the girls were murdered so very quickly. Maybe, it was a wrong assumption by them - who knows.
