What a putz. From CNN:

The suspect, Timothy James Chapek, was in the bathroom taking a shower when the homeowner returned to the house Monday night, Portland police said in a statement.

Accompanied by two German shepherds, the homeowner asked Chapek what he was doing in the house.

Chapek locked himself in the bathroom and made an emergency call, police said. He said he had broken into the house, the owner had come home, and that he was concerned the owner might have a gun.

The homeowner also called the police to report that he had found a man in the house.

This dude should be the poster child for keeping a gun at home for self defense. Scare away the criminals. Thankfully, the police did not release whether the homeowner had a gun.
