JEFFERSON - A man accused of killing an off-duty Oconomowoc Police Officer and her boyfriend made a second court appearance, where gut-wrenching testimony came from witnesses about the murders.

A judge decided there is enough evidence for Andrew Wirth to stand trial.

Wirth was surrounded by extra Waukesha County Sheriff's deputies after his first appearance in the case of the murders of Officer Jenni Luick and Gregg Peters.

Deputies had to restrain, taze and take Wirth out of court in the first appearance.

This time around, there were no incidents after his hands had been cuffed, ankles shackled and a stun belt placed around his waist.

Witnesses took the stand, saying Luick had playfully grabbed Wirth's rear end in a bar.

"He turned and really glared at her," said Carol M. Blasier. "Jenni could tell that he was upset."

Witnesses say that Luick and Peters left the bar, but returned. Tensions escalated, and the group went outside.

That's when, one witness said, Wirth pulled out a gun.

"The man with the gun said, 'stop being so f'ing stupid,' " said witness Brian Trader.

Witnesses say Wirth shot Peters first, then Luick, point blank.

Peters was still alive when paramedics arrived.

"He said, 'He shot me three times. I begged him not to, but he shot me three times,' " said paramedic Robert DeWolfe.

Police arrested Wirth a short time later, and said that he confessed to the murder.

"He said the male subject came after him and he shot him," said Fort Atkinson Police Sergeant Thomas Stewart.

Wirth is a member of a motorcycle gang. He has the words "nothing to lose" tattooed on his neck.
