If the river was thoroughly checked along the entire stretch of River Rd., the most probable explaination has been eliminated. There is certainly the chance she is hidden in vegitation off the road. She might turn up after the leaves fall, which should be in the next couple of weeks. (there was a young man in Calif who disappeared after a party. Two weeks later, after an extensive, highly publicized search, His body and the car were found in some decorative foliage along an urban freeway on the expect route from the party to his home)
The most important clue is her phone. We know it was "off" within a few minutes of the "arguement" with Chrystal. The phone either went "off" through some "mis-adventure" or Toni turned it off (or let the battery run down). By interviewing Toni's friends and family and checking cell phone records in the prior weeks, LE could tell wheter or not Toni kept her phone "on" pretty much all the time. If Toni was in the habit of leaving her phone "off" all bets are off; anything could have happened at any time. She could have had an accident or been abducted or, perhaps, taken off on her own. If however, she is like most folks and keeps her phone "on", It pretty much limits what could have happened. We must assume the "mis-adventure", almost certainly an accident, occured right after the argument.
Hopefully, if this is the case, Chrystal was asked for the approx time between Toni taking off and the first call. Then a maximun distance that Toni could have driven could be established. The search would be restricted to that range alonge the probable/possible routes ONLY where there is vegitation or water where a car could be hidden and no guardrail or other barrier.
It is not unheard of for young women, driving alone at night, to be hikacked. I have never heard of a case where the car was taken and made to "disappear". I find it unlikely that a hijacker would make a point of turning of a cell phone at the time of a hijacking. (If they even thought of the phone, they would probably pitch it). I think it is improbable that the "mis-adventure" (that shut the phone off) was a hijacking.
