If possible, the terms of the reward will eventually need to be changed to 'return of MT (dead or alive) and/or info leading to arrest and conviction of parties involved'; this alone could generate freelance PI interest, and considerably
up the ante for those who might be paid to look Those who have donated, and will in the future, could be asked if they concent to to the change. I'm curious as to what are the terms for the first $2,000 posted. If there is currently a two-tier reward for MT's return, then increasing that lower tier for other than MT's safe return should be doable, with donor approval. I do not think that MT's father is out of the fight yet. He is just going back home to regroup. As his denial changes to anger, I am curious to see what resources he brings to the hunt for MT. He comes from a community with incredibly deep pockets, and with the interest in this case, with that kind of money anything is possible!
I think that LE was deliberately vague about the terms of the reward at the last PC, to increase the response. At this point, I do not like the terms of the current reward, as it may appear like too much of a bait and switch to those who actually know what happened to MT!
The most radical thing that I would do, would be to allow the award to be paid to the perpetrator's next of kin, if he turns himself in along with MT (in whatever condition - if that is possible). I know that US law enforcement would not allow this, if they have a say so in the matter, and for good reason. However, with enough money, almost anything is possible, even if it has to be done on the international level.
