Ha! I quoted myself
I think this early presser is extremely important. I know cases evolve, they are fluid, etc. But it's revealing what some of the comments were just one week after the murders.
It's like taking a multiple choice test in school, they always said, go with your first gut answer if you're not sure.
The above quotes are answers to questions posed after the presser. At that time, it's pretty clear to me, they didn't think this murder was a chance encounter, meaning, they had reason to believe the murderer was there that day, AND the girls were they that day, for a reason.
At that time they did NOT think it a serial murder situation.
Lastly, they alluded to more than one person involved.
