Woman last seen at O'Hare says she's safe

Leslie left a comment yesterday on my short post on Sumei Hu pointing me to an article in yesterday’s Chicago Tribune.
According to the Chicago PD Sumei Hu has contacted her family. Her sister-in-law told the Tribune that Hu had contacted the family on the phone Wednesday and told them that she was in the Chicago area and was safe. Sharon Romenesko (the sister-in-law) said it was unclear what she had been doing for the last week.
As Leslie said, very fishy.
Either there is a bit more than meets the eye here or this is just a matter of someone leaving their husband and it should be a case of ‘media butt out’.
