A Washington state woman was sharing her home with someone and didn't even know it.
Velma Lellen called in a repairman because she thought her furnace was on the blink.
The repairman found that someone had cut into the duct work to keep warm in the crawl space.
The other odd thing, for the past year, there's been an odd smell in the home.
"I couldn't figure it out, " sid Kellen. "I can't say marijuana. I don't know what marijuana smells like, but it was worse than cigarettes.
Who ever had been staying there liked to get "their party on" based on the beer cans and liquor bottles found in the crawl space, not to mention the odd smell.
