NEWMAN LAKE, Wash. -

A jealous ex-boyfriend broke into the Newman Lake home of his ex-girlfriend's boyfriend early Sunday morning and was shot and killed by the homeowner.

Spokane County Sheriff deputies say a Honeymoon Bay homeowner was acting in self defense when he shot the armed intruder, identified late Monday afternoon by the Spokane County Medical Examiner as 43-year-old Sean M. Parsons.

Parsons had been served a no-contact several hours prior to the shooting, but that didn't stop him from taking a shotgun and a pistol to Doug Snarski's Honeymoon Bay home to confront his ex-girlfriend and Snarski.

Early Sunday morning around 1 a.m. Parsons slipped into the couple's home, when he started calling out to the couple.

"All of a sudden we heard his voice down here saying 'Where are you? Come out' and that's when she said that's him. She recognized his voice," Snarski said.

So he grabbed his revolved and stood at the top of the stairs while Parsons detailed his intentions to kill him and his girlfriend.

"He goes 'Nobody's getting out of here alive. I got 24 rounds for my shotgun, I plan using them all,'" he said.

At that point 911 dispatchers were on the phone - Snarski had already dialed them - and listening as he tried to defuse the situation.

"I'm trying to talk him down, just leave, don't worry about it, it'll be OK but he was on a mission to kill," he said.

At that point Parsons fired a pair of shotgun blasts at Snarski, peppering the top of the stairwell with buckshot. Snarski decided he'd hold his fire unless the gunman tried to reach the second floor.

"I just laid on the ground around the corner and watched his shadow come up with the lights and as soon as I knew he had hit that last step I just pointed up and let him have it," he said.

It was the first time Snarski ever fired his revolver.

Parsons was shot and killed; the spot where he fell now marked by black plastic which covers the spot where the man bled to death.

Snarski took no pleasure in the shooting, but the damage to rounds of buckshot fired at his bathroom door is a grim reminder of what could have happened if he hadn't defended him and his girlfriend.

"Like I said I played it right to the end. I tried to talk him down. I mean nobody wants to kill anybody but it came down to either me or him," he said.
