A former bookkeeper for an oilfield company in central Alberta has been charged with stealing more than $1 million from her employer.

Blackfalds RCMP began to investigate in October 2012 into a report that an employee appeared to be altering financial documents and taking money from a business in Red Deer county.

Police did not name the business or where it is located.

Mounties say the employee was employed by the company from 2006 to 2011 and was in charge of bookkeeping, accounts receivable, payroll, and day end returns.

It is alleged the employee stole the money over the five years she worked for the company.

Shelley Davidson, who is 36, of Cochrane, is scheduled to appear in provincial court in Red Deer on Sept. 20 on charges of theft and fraud.
