I'v been following the case since the very beginning and obviously I can't speak for everyone but personally I doubt it. My own opinion is that the family of her baby's father knows more about her disappearance than they've said. TOTALLY unrelated (sarcasm), it's interesting and pretty surprising we haven't heard from JDT since this discovery.

Exactly one month before DNV was last seen she made this wonderful goals list, things were really looking up in her life, she was getting more and more time with her daughter. It's always possible it was self inflicted but I'm leaning towards someone did this to her.
