"I thought someone broke into the house, but I didn't think they were still in the house," said Clay Parkman. "I saw the guy right there."

The intruder then ran into a bedroom and to a window. Parkman said he chased the man and then "acted on instinct."

"I jumped over the bed and pushed him out and hard as I could."

The man plunged 20 feet from the second story.

"He didn't scream or anything. He was just looking at me the whole way down," Parkman said.

After landing on his back on the concrete, the man got up and began to run.

Clay Parkman's twin brother Christopher ran out of the house and jumped into his car to chase the man. Christopher Parkman said he chased the man through woods and into a creek.

"I'm about to catch up with him and tackle him and he stops and says, 'I'm going to stab you.' So, I decided to back off a little bit," Christopher said.

Police quickly arrived and arrested the man.

The man complained of back pain but was not seriously hurt.

He is being held in the Thurston County Jail.
