I completely understand that LE has to hold back certain pieces of information to protect the integrity of the investigation. And I respect that some details shouldn't be released out of respect for the victim or to protect the identity of certain witnesses. That being said, I hope LE learned the following from releasing this info:
1. LE couldn't figure out who owned this car after 4 and a half months of investigating. However, they were able to find the owner and rule this person out within three days of releasing this information to the public. Releasing info to the public can be a tool!
2. The public still cares about this case and will help if given the necessary info.
That being said, releasing the following info would really help:
1. What was the cause of death?
2. Why is it that they don't believe there is any danger to the public with this case not being solved? The fact that they don't believe the public is in danger tells me that they think his death was the result of a specific confrontation, and that the person who did it is not running wild with plans to do this again. But I don't know that with any level of certainty because they haven't provided further detail. (This is one of those things that could fall under the "protecting the integrity of the investigation" umbrella, but it would give all of us a lot more clarity if they would just tell us.)
3. Was it a "tip" or an "interview" that allowed them to find the body? If it was a tip it could just mean that the people at the RV place told them he was there. If it was an interview it means that someone knew he was killed there or dropped there, and gives me much more confidence that they are close to solving the case. (Again, this could be a "protecting the integrity of the investigation" issue, but after almost 5 months of investigating I think it is a fair question to ask.)
My theories (with applicable eggs in parentheses - updated since the last time I did this):
Beaten over dispute while buying party supplies (5)
Hit by car (4)
Fight at party (2)
I'm still holding one egg and reserve the right to move eggs around as more info comes available.
