I don't think the bigger agencies (DEA, IRS, etc...) would want David Morgan discussing anything in reference to what they are themselves investigating. Doing so could jeopardize their investigation and possibly tip off the people at which they are looking. Jmo
BINGO. Notice at the end when re-asked about other agencies involved, Morgan said "to the best of my knowledge, no" (or pretty close to that quote)
That's the same Morgan who said "to the best of my knowledge the DEA is NOT involved." Then it became "I won't address that" to "Yes, we called them in to help because I had to pass along information to them."
He also said in today's A.M. press conference that "to the best of my knowledge" no other agencies were involved. :\
BTW, WEAR TV side at the start of their 11 a.m. newscast that the reason the press conference was delayed was because The State Atty and the Sheriff could not agree on what information could/would be released.
These two are not 100% on the same page. One minute one says "this is it" and the other says "we're still looking."
But, oh how I did love the comment "and people in Hell want ice water" by Morgan yesterday.
ETA: It makes legal sense for them to release as LITTLE information as possible so those involved down the road don't realize they're being sought. Also, it makes sense to even give some 'misguided' information to those POIs to make the confess.
