The woman arrived at her home on Montego Drive at 10 p.m. on Wednesday, March 5, and parked the car in the garage. She closed and secured the garage door, she told police.
"The next morning she got in her car, went to work, discovered that the $4,000 was missing and notified us," said Lt. Mark Williams of the Danville police.
"She said that she had taken it out to place in a petty cash fund at a business that her husband owns," he said.
Police found no evidence of a break-in at the house - no kicked in door, no smashed windows. The incident was reported as a lost property case.
"I wouldn't recommend leaving large amounts of cash in a vehicle in a garage for a variety of reasons," said Williams.
Police processed the scene for fingerprints but were unable to locate any. Williams said it's a possibility that the money was stolen, but with no evidence of criminal activity, there's not much they can do.
