It's one down, three to go in the case of the stolen Cadillac Escalades.

All four SUVs were stolen last month from Horton Automotive in Monroe in what police have called a professional burglary. The thieves were able to slip past motion detectors at the dealership, get the keys to four Escalades, disable the on-board security systems and drive the vehicles away.

One of the four has been found, The Walton Tribune reported. Finding that vehicle gave investigators clues to finding the others, Monroe police Chief Keith Glass told the newspaper.

“We are now working with several jurisdictions — from local to federal agencies — to track down the suspects and the three remaining Escalades," Glass said.

The stolen SUVs are valued at $75,000 each.
