A Knoxville man called 911 Monday after finding quite a surprise under his house:  a couple of half-naked men apparently trying to make drugs.

Paul Mohlman was watching television at 10:00 a.m. Monday when he heard a loud thud in one of the bedrooms.

"I thought something fell.  I walked in and there's an old radiator connection and pipe on the floor. How on earth did it get there? There's a hole in the floor where the radiator pipe used to be, and I can see there's light coming through the hole from the crawl space.  I look in the hole and there is an eyeball staring back at me. A green eyeball," said Mohlman.

Mohlman said when he asked who the man was, the answer was incoherent.

"At first, I thought he might be someone the landlord sent for maintenance. Then I could see through the hole he had no shirt on, no shoes, was really dirty, and clearly a person on some kind of drug," said Mohlman.

Mohlman called 911 and warned the dispatcher his story would sound odd.

"I said, 'This is going to be the strangest call you've had all day, I guarantee it. There's a half-naked man under my house and I'm not sure what he's doing.' Knoxville Police were here in seven minutes," said Mohlman.

Mohlman warned the intruder he was armed with a rifle and he did not want him beneath the crawl space.

"I did not go around to the side of the house because I did not know if this person was armed. I had my gun for my protection, not because I wanted to confront this guy and shoot somebody," said Mohlman.

KPD searched the crawl space and found a 24-year-old black male, but did not find the white male with green eyes Mohlman saw through the floor.
