MARINETTE - The calm demeanor of a female Marinette convenience store clerk and the poise of a male customer helped law enforcement personnel apprehend an armed robber in quick fashion Monday night.

A 19-year-old Milwaukee man was arrested less than two minutes after he robbed the Holiday Gas Station, 4010 Marinette Ave., at 10:55 p.m. He barely got out of the parking lot.

"It was perfectly handled. She did what she had to do and so did the customer," according to Marinette Police Chief John Mabry.

So did the officers.

While responding to a silent "hold-up alarm" and en route to the scene, officers were informed there had been an armed robbery and a suspect had pointed a firearm at the clerk and demanded money from the cash register. The suspect also ordered a store customer to turn over money.

Mabry said the clerk, whose name is not being released, was able to diffuse a situation that could have been far more serious. He said the robber wanted the customer to exit the store with him.

"They both told him 'no, you got what you want, now leave," the chief said. "Had the customer left the store it could have been much worse."

The clerk gave a detailed description of the suspect and the direction he was headed. The description given was of a lone male wearing a mask and armed with a handgun, fleeing on foot.

Mabry said the suspect was spotted leaving the store by two Marinette County Sheriff's Department deputies who were doing an after-hours check at a nearby business. A Marinette police officer aided in the apprehension and another MPD officer went into the store to check on the clerk and the customer.

Larry Pitcher, the manager at the Holiday Gas Station, said he was limited on what he could say because of corporate policy, however, he did praise the store clerk.

"Everything by my associate was handled well," he said. "There were no injuries and everybody is safe. It was a good ending."

The suspect was lodged in the Marinette County Jail on two counts of armed robbery and two counts of recklessly endangering safety. Formal charges are pending through the Marinette County District Attorney's Office.

This was the first armed robbery in Marinette since May 31, 2012, when the ValuCare Pharmacy on Main Street was robbed. That suspect also was caught quickly and is serving a 13-year prison sentence.

Mabry singled out the response time in Monday's robbery.

"Hopefully we're sending a message (to criminals) about committing a crime here," he said.
