"I went to the post office to buy some stamps and I could have sworn I had money but there was no money there," Barbara said.
Then she noticed something else was missing from her car.
"It was a ring I had made up right from money when my grandmother passed away; I had some stones added to it," Barbara said.
The ring was worth about $7,000. Medford Police believe the same thieves may be responsible for thefts in June. There have been laptops stolen, cell phones, car batter chargers, cash and credit cards.
Raymond Rodden said his $600 GPS was hidden in his car, but he made one mistake .
"I tend to put it in the center consul at all times, but the car was unlocked," Raymond said.
Police say all 40 victims had left their cars unlocked.
The residents Action News spoke to say until now they never had any reason to believe leaving their car unlocked was unsafe.
Police say they did arrest three teens last week in connection with some of the burglaries, but they believe there are still more people responsible.
Even the local country club put a warning out in their newspaper after a member's credit cards were stolen from his car and used hours later.
