A safe taken from a car dealership - the third safe stolen or broken into here in nine days - was recovered Thursday by police in a wooded area.
Several other businesses have reported file cabinets being broken into during recent burglaries, apparently by thieves searching for money, police said.
"There's no way of knowing at this point in time if they're connected," said police Capt. Carl Bergh. However, he called the high number of those cases "unusual."
The safe stolen from Robideaux Motors apparently had been emptied before detectives retrieved it Thursday. Another safe taken from a doctor's office last week has not been recovered. A safe in the third burglary was cut open, but not taken.
Police have no suspects, but said the same person or group could be behind the string of safe thefts because of the number and relatively short time period.
"That's in and of itself an indication that possibly it's the same person," Bergh said.
Following the most recent burglary, employees at Robideaux Motors on Sherman Avenue discovered pry marks around four doors when they got to work Wednesday morning.
Desks in two offices had been rifled.
Imprints in the showroom carpet marked the spot where the safe had been the night before. A set of golf clubs in one of the offices was not disturbed.
Lost with the safe were an unknown number of financial documents, according to a Coeur d'Alene police report. Dealer license plates also were swiped from a desk drawer.
Two other items stolen from the business were not disclosed by police.
On Sept. 12, Duncan's Nursery on Kathleen Avenue was ransacked and the safe overturned and cut open. An unknown amount of cash was taken from a money bag kept in the safe. A white cockatoo, a bird stand, and food for the bird also were among the items taken.
Early last week, thieves left the dial behind but stole a safe from a Coeur d'Alene doctor's office.
Police investigated a similar run of safe burglaries last year.
At least five Kootenai County businesses had fallen victim by mid-December during that string, losing more than $10,000.
