EVERETT — Prosecutors say what started out as a friendly challenge ended in bloodshed when a man teased a Monroe woman about having smelly feet.

Dallas Amber Smith, 18, is accused of stabbing a man in the back at a party on Sept. 7. Smith first became upset when she was unable to do a back flip, Snohomish County deputy prosecutor Janice Albert wrote in court papers filed Wednesday.

Smith and others were gathered at her ex-boyfriend’s home south of Monroe, watching a movie and drinking.

She boasted to party-goers that she was good at doing back flips and that she could do one off anything, court papers said.

A man, 19, challenged her to do a flip off the deck. Smith took off her shoes and attempted the maneuver. She couldn’t do it. That’s when the man laughed at her and told her that her feet smelled, Albert wrote.

Smith started to playfully wrestle with the man, rubbing her socks in his face. She started hitting him. After several seconds, he pushed her away, Albert wrote.

She grabbed her coat, picked up a steak knife and headed for the door. On the way, Smith walked up to the man and stabbed him in the back, court papers said.

The man and others called 911. A sheriff’s deputy found the man sitting on porch with the knife sticking out of his back, the blade buried a few inches in. His lung had collapsed from the stabbing.

The man is expected to recover from the injury.

Police arrested Smith at her parents’ home. She denied knowing about any stabbing and declined to speak with investigators.

A witness told police that Smith came to his house that night and told him that she had hurt someone and she was in trouble. She told him someone had taunted her.

Smith, who has no criminal history, is charged with second-degree assault with a deadly weapon.

She posted $50,000 bail and was released. On Wednesday a $250,000 warrant was issued for her arrest after Smith told a detective she was leaving for Australia on Saturday, and planned to be gone for several months, Albert wrote.

She surrendered her passport to a sheriff’s deputy on Thursday and the warrant was quashed.
