He did not say theories, he said details. There is a big difference as to what peoples theories are and guessing what some of the details that LE is not telling. IMO this is why they did not release the COD or autopsy report
Whoever did this is probably the only person who knows some details of this case. A lot of people think they know and there's are a lot of people in the area, there is a lot of information out there that is known but sometimes it's embellished or over-exaggerated and we just talked to the family the other day to try and squash some rumors.
But the public needs to know that whoever did this, they are the only ones that know, one or two people...however many, we don't know, but if it's one person, he's the only person who knows this ... he's the only one that knows the details...(talks a bit about protecting the integrity of the investigation and going to trial) and people guess and sometimes they get close.
