The strange odyssey of Melba and Alicia Doshier: What happened?

http://www.foxnews.com/story/0,2933,119006,00.html

This story just sorta disappeared. The facts appear to be:

a) Mother and daughter were evicted
b) Mother and daughter take road trip
c) Mother dies somewhere along the way
d) Mothers remains are discovered in the car in a Wal-Mart parking lot.

Did they ever release any info on when during the trip the mother died? Presumably the daughter would have known.

Did she say why she continued the trip instead of making arrangements for her mother?

Is the daughter under any kind of psychiatric care?

Will there be any charges?

News stories say she is under psychiatric evaluation:

A quick googling showed no new stories.
