Finding the fumigation warning sign moved from the tent and a sliding glass door unlocked, an employee of the extermination company became alarmed. It was during the final walk-through of the Goleta residence following the treatment when the employee discovered a person lying on the couch inside. Fearing the worst, the employee began yelling until finally the subject stirred from his slumber.Law enforcement called to the scene met with the subject at 9:15 a.m. The subject, the son of the homeowner, explained how he needed a place to stay since leaving a substance abuse treatment center. Knowing the home would be vacated during the fumigation, and needing a place to sleep, he decided to sneak in over the course of the night.The man, 36, was arrested for criminal trespassing.
