A suburban Kansas City woman who had at least $100,000 in items stolen from her garage thinks the thieves used global positioning technology to determine when she wasn’t home.

The Overland Park, Kan., woman owns a jewelry store and believes her loss in the March burglary really was closer to $300,000. The jewelry business owner lost jewelry, purses, wallets, luggage, coins and fur coats in the heist.

She said after the burglary, GPS devices were found on her vehicle and one owned by her son.

A 36-year-old man was charged in connection to that and other burglaries. He is out of jail after posting a $100,000 bond.
