IMO, It should be helpful to police to see who he communicated with last. Maybe it will indicate if he was meeting up with / getting a ride with someone. Glad that the phone is functioning, and wasn't smashed, as in some other similar cases. Do volunteer searchers wear gloves? Are they usually trained to handle found objects so as to preserve fingerprints and DNA? It's possible someone other than Achim handled his phone. I'm a bit surprised the volunteer turned it on rather than bagging it and giving it directly to LE. I wonder if that was due to lack of training, due to mistrust of LE, or due to something else. In the Joey LaBute search, I think I recall reading that volunteer searchers were trained in collecting found objects so as to preserve any potential evidence. MOO.
