Armed man shot to death by officer outside market

LAWRENCEVILLE - An armed gunman was shot and killed Tuesday night in a grocery store parking lot by a member of the Gwinnett County Special Weapons and Tactics unit.

Gwinnett County Police Department spokesman Cpl. Darren Moloney said police were called to a domestic disturbance by a 36-year-old Lawrenceville woman who said she was being threatened by her ex-boyfriend about 11:30 p.m. Tuesday.

Moloney said the ex-boyfriend, identified as 35-year-old Duncan Edward Kaulbach of Bethlehem, fled from the victim's home after threatening her and was found armed with a handgun at a nearby Publix supermarket at Old Peachtree and North Brown roads.

"Officers were able to keep the armed gunman in the parking lot while stopping traffic and clearing the scene," he said. "Because of the man's behavior and the fact he was armed with a handgun, the SWAT unit was activated."

Moloney said SWAT crisis negotiators attempted to talk to Kaulbach to convince him to drop his weapon, but Kaulbach was shot after he pointed his gun at officers.

He said Kaulbach was pronounced dead after being transported to Gwinnett Medical Center.

"Officers must have a reason to shoot, an opportunity to shoot and must be in direct jeopardy," Moloney said.

Although Moloney said he was unsure how many times Kaulbach was shot, he said the shooting is part of an ongoing investigation by members of the department.

He said the officer, whose name he was not releasing, was put on paid administrative leave as per department policy. Moloney added he was unsure how long the officer would be on leave.

Investigators believe Kaulbach had a history of domestic violence as well as mental health issues, Moloney said.

He said Kaulbach was incarcerated at the Gwinnett County Detention Center in April 2005 and July 2006 and charges were related to domestic violence and involved the same ex-girlfriend.
