(Happy Valley, OR)  --  Clackamas County sheriff's deputies are looking for a woman who entered an occupied home in Happy Valley and stole hundreds of dollars.  Authorities say the homeowner's son was in the house at the time, listening to music with headphones on, and wasn't aware of the incident.  Deputies say surveillance video captured the woman walking into the Southeast Mia Garden Drive house yesterday through an unlocked door.  They're hoping to use the images to ID the suspect.
