A Casper woman is denying that she tampered documents and altered the odometer on a vehicle that she sold.

Angela Zambai has pleaded not guilty to charges of fraudulently altering a government record, fraudulently altering a certificate or title, unlawful selling of a vehicle and obtaining property under false pretenses.

Investigators say in January 2012, they were contacted by a car dealership owner, who had purchased a vehicle from Zambai.

Upon further inspection of the vehicle title with the Natrona County Clerk's Office, a discrepancy was discovered in the mileage on the odometer, and that it was off by 250,000 miles.

The clerk's office also said that the title appeared to have been altered, and that the last digit of the odometer reading was missing.

Investigators were able to contact several previous owners of the vehicle and obtain records to back up the discrepancy claim.

When interviewed, Zambai said she was a messy person and that she accidentally cut the title with scissors.

When she purchased the vehicle, she did not pay attention to the documents involved, and didn't check the mileage herself.

An auto salvage yard owner said Zambai once purchased a transfer case and rear drive shaft for a different vehicle, but it was possible that the parts could have been used for the vehicle in question.

Zambai is free on bond awaiting trial.
