OKLAHOMA CITY, OK (KFOR) — Police are searching for an intruder who left an unpleasant surprise in an Oklahoma family’s backyard.

The would-be burglar left empty-handed, and the family may have never known he came if it weren’t for their dog Ziba and her crime snuffing sniffer.

“We let our dogs out for the morning, and she immediately came right back in, my daughter hollered at me `Something`s all over Ziba!,” said Shauna Walker. “Realized it was human poop, so I called my husband, and I was like check the cameras, I think someone has pooped in our backyard.”

Surveillance cameras captured images of the suspect, showing him walking around the house and milling around.

“There`s a distinct difference between the way dog poop smells, and human poop smells,” she said. “He had cleaned himself with the leaves, it was pretty obvious.”Read more: http://bit.ly/1pgqFdd
