Well, apparently, she had an argument with her boyfriend. The article at the link below illustrates how she went to Atlanta with the kids to visit the boyfriend a few days ago, and then ended up having a missing persons report filled for her on Tuesday of this week. Where had she been all week, and what was she doing? Drugs???
"Sandra Hawes says Michelle went to Atlanta to visit him with the two kids on Monday, returned Tuesday on a Greyhound bus with Jordan and Shakayla and wanted to go to Aiken, reportedly looking for her boyfriend again. Michelle's family says they last saw her at an Aiken KFC Tuesday. The family says they filed a missing person report on her Wednesday in Aiken. News 12 is still working to obtain this report. Sandra next saw Michelle Thursday, walking down Lumpkin Road with the children towards the store. Her aunt wanted to help her out and give them a ride, but couldn't because she was driving a school bus and feared loosing her job. "
