LOUISVILLE, Ky. -- A Louisville man has pleaded guilty to robbing a rural Indiana bank at gunpoint, and police say he could have pulled it off if not for a minor mistake -- making a wrong turn, WLKY-TV reported.

"He kept wanting to know, 'How'd you catch me? How'd you catch me?' "said Washington County Detective Capt. Jeff Topping.

Police said that less than an hour after Jose Arce held up a bank, he was surrounded by police.

Investigators told WLKY where Arce went wrong.

"I thought he'd done a real good job," Sheriff Claude Combs said.

Combs admired Arce's planning. He had researched banks in the area and chose to hit the Campbellsburg National City Bank. The robbery went down without a hitch. Police said Arce had a police scanner and an escape route.

One detective said it was the perfect crime -- until the suspect deviated from his plan.

"The mistake he made was a wrong turn. That's what the mistake was," said Combs.

Arce told police traffic congestion and panic forced him to make the wrong turn. The decision cost him nearly a half-hour.

That gave Topping and a handful of deputies plenty of time to get into place.

And then Arce made another mistake, police said. He went through the trouble of renting a car in Kentucky and stealing an Indiana license plate to put on it.

"If he had stopped anywhere along the line and switched the plate with the Kentucky one back on, chances are he would've got away," said Topping.
