BOERNE - Brazen car thieves drive off the lot in a Dodge Challenger as employees watched, not realizing anything was wrong. Sheriff's deputies say some time Wednesday night, burglars stole the key lock boxes off four vehicles at the Boerne Dodge Chrysler Jeep dealership. Then they returned at about 8:30 Thursday morning.

"Several individuals pulled up to the dealership in a white pickup and jumped out of the bed of the pickup and had the keys to one of the Dodge Challengers, which happened to be up on one of the risers," explained Lt. Shad Prichard.

He said the two men had the keys to the Challenger, got in and drove it off the riser and off the lot, with a little help from the two men in the white pickup.

Several employees witnessed the theft but didn't realize anything was wrong until the car was driving off the lot.

"One of them (the thieves) had on a shop shirt, like he was an employee of the business. Because they had the keys, it didn't raise any suspicions that maybe they were doing something wrong. Everyone assumed they were doing something they needed to be doing," he said.

It's apparently a pretty successful technique, because this is not the first time someone has absconded with valuable merchandise by acting like he was supposed to be there, and it probably won't be the last. Not by any stretch of the imagination.
