BELLE ISLE- Orange County deputies ramped up their search for a 36-year-old mother of twins who has been missing since Monday.

Deputies and a K-9 Unit searched the home of Michelle DuBois Wednesday afternoon in this community southwest of Orlando. Her husband, Chris DuBois, was outside during the search.

The Orlando Sentinel reported that a sheriff's spokesman did not say what investigators were looking for.

Officials say the woman was reported missing Monday evening. Chris DuBois told deputies he took their children to school about 10:15 a.m. and she was gone when he returned 45 minutes later. She left behind her wallet and her vehicle was in the driveway.

According to a report, DuBois told deputies he had searched near their home before reporting her missing.
