YAKIMA, Wash.-- A Yakima man showed up at his neighbor's house with a bloody knife in his hands. He told the neighbor he attacked two people who tried to break in. Officers who got to the scene at MacLaren and Tieton weren't sure who had the knife originally. The man said it was the intruder's. Police tell us the whole thing seems suspicious, but no arrests have been made.

" Its disturbing, extremely disturbing," said the neighbor. "What are you going to do? It's Yakima. It's not just happening here, it's happening all over."

In 2008, there was a murder at the same home.
