Some more things that don't make sense....Her daughter is getting married. I have a hard time imagining a person who is going thru so much thought and planning to commit suicide would do it right before a wedding. That is so hurtful to the daughter and family. I could better understand it if the suicide was an impulsive decision. But this was very drawn out - calling family, police, etc. I wonder if she was just wanting attention (make up kidnap story), but then realized police were about to find her with GPS tracking, and felt shamed and knew the gig was up, so killed herself. That doesn't sound plausible either though.
Really - no scenario here makes any sense.
