Ex-Miss Washington Stormy Keffeler appeared drunk -- and had blood on her shirt and hands -- when cops arrived to her boyfriend's Seattle apartment after he had been stabbed ... this according to the police report obtained by TMZ Sports.
Cops say ... when they arrived to the home of MLS player Marco Pappa on December 17th -- there was blood all over the walls ... and also on a knife in the kitchen.
Pappa had a 2-to-3 inch stab wound on his torso -- and later needed surgery to treat the wound -- but when asked at the scene if his beauty queen girlfriend was the attacker, he was adamant she was NOT.
