Tuesday afternoon, two masked robbers made off with several bags of jewelry. But the quick-thinking store owner wasn't about to let them go without a fight.
It happened at Thalheimers Jewelers located at 3200 Tamiami Trail North in Naples.
When store owner Sandy Thalheimer saw a jewelry delivery man being held at gunpoint in his parking lot, he knew he had to do something, and fast.  "They pulled up real fast, much faster than you pull into a parking lot," Thalheimer said. "I saw they had masks and I said, oh, we're getting ready to get robbed."
 
As the suspects jumped into their getaway car, Thalheimer, who happened to be watching from his truck., sprang into action. "I said, no, and I backed up a little bit to get a run, and as they pulled out, I just rammed them. Hit them pretty hard. I've got a big truck," Thalheimer said.
 
"The alarm was going off in the car, the truck was up against it. All the air bags were blown," witness John Vansteenis said.

But Thalheimer's truck was stuck. Sitting on his gun, he knew he had to make another quick decision.
 
"The first guy was over there probably 20 feet away.," Thalheimer said. "When he turned, I fired, and then he took off really quick. I don't know if I hit him or not. The second guy over here started shooting at me, and I started shooting at him, then they were gone and I was out of bullets."
 
Steve Blount, an attorney who works in Thalheimers building called 911, and watched the whole thing unfold from his window. "A little orange red SUV came speeding down the road and picked them up, down by the empty lot," Blount said.
 
That SUV was later recovered near Creech Road. Police believe the suspects ditched it for yet a 3rd getaway vehicle
Even though they didn't actually rob the store, but the sales person, Thalheimer doesn't want that happening on his property.
 
"You don't have time to think about being afraid or anything like that," Thalheimer said. "Everything happened really quick. You just do it."
 
Thalheimer is no rookie gun owner. He actually runs the Sandy Thalheimer Defensive Gun School.
It's unclear just how many shots were fired. Luckily, no one at the store was injured.
