The chances of him being found alive now are exceedingly slim, and LE has already said they’ve exhausted all resources in the absence of additional information. His father is a pastor and likely has a lot of responsibilities to tend to during the holidays, and friends may not be readily available for the same reason.
Often in cases where family and friends pursue independent action and media coverage, it’s due to 1) suspicion of foul play, and 2) without the explicit blessing of LE and/or with the belief that LE hasn’t been proactive enough. There’s no evidence of foul play, and, IMO, the family believes LE & SAR have been and continue to be proactive. If evidence of foul play were to emerge, I’m sure media coverage would ramp back up.
I personally think that understanding more about Jason’s state of mind leading up to the accident would increase our understanding of how the accident happened and what actions he may have taken afterwards. However, I don’t anticipate that will be reported in MSM unless it corresponds with finding him in the near future. JMO.
