UTICA, N.Y. -- Deputy Kurt Wyman was the first officer to respond to reports of a domestic incident at the Knoxboro home of Christian Patterson. After a physical argument with his girlfriend, police found Patterson armed in his garage and unwilling to back down. Patterson would eventually fire three times at officers.

Prosecutors believe he was ready to fire his weapon early in the stand-off, judging by his response to a friend's phone call inquiring if he was okay.

"The answer he gets is, 'No. I'm locked and loaded. I have my guns. I'm not going to jail. I'm not leaving my house,’" said Oneida County First Assistant District Attorney Michael Coluzza.

Patterson's attorney says his client didn't intentionally shoot Wyman. He says when officers fired less than lethal rounds at him, Patterson was sitting on a stool backed against a wall.

"He went over and then he came back and the gun went off," said Chief Public Defender Frank Nebush.

Prosecutors say Patterson was armed with a pump shotgun, meaning it would've taken specific action to fire each bullet.

Patterson's longtime girlfriend said on the stand that while there was a history of physical violence in the relationship, she'd never felt the need to call 911 on him until June 6, 2011.

The jury heard testimony that the fight started because of Patterson's suspicious of infidelity and turned into a physical fight, with Patterson breaking the glass door on their gun cabinet.

"And when he did that with his arm, were you concerned?" Secor was asked on the stand.

"Yes," she replied.

"Why?"

"I thought he was getting a gun out to kill me," Secor responded.

The court also heard from the neighbors Shannon Secor ran to for help and who ultimately called 911.
