Walmart. Save money. Die faster.
UPDATE (6/13/13): Three men were involved. One of them was an employee of the Walmart. They used a realistic-looking BB gun.
From an article with details on how the crime unfolded and how the suspects were caught:
Three Milwaukee men are in custody in the armed robbery early Friday morning of the Walmart Market in Wauwatosa, according to police reports.
Two of the men are accused of driving to the door of the store and carrying out the holdup while the other waited with a backup vehicle. After the robbery, they swapped cars and transferred their guns and other evidence from one to the other, to "throw off police," one of them confessed.
The robbery was something of an inside job, according to the suspects' statements.
Two of the suspects, one 20 and one 26 years old, were discussing robbing a bank or business Thursday night. The third man, 23, told them that he could plan and take part in a robbery of the Walmart at 3850 N. 124thSt., because he knew the place well. He had been fired from his job there a week before.
He drew a map of the interior and told them about the store's policies on storing money. He and one of the others donned all black clothing and took two guns, one a loaded pistol and the other a short rifle. ...
Several said that they believed the rifle one carried was in fact a BB gun, and the 18-year-old felt certain of it, saying he was close enough he could see BB's in the magazine of what he told police was an AK-47 lookalike..
