A top administrator in the Scottsdale Unified School District resigned amid an investigation into a conflict of interest.

While Laura Smith was the chief financial officer at the Scottsdale district, she signed off on paperwork related to a consulting firm she had a stake in with her sister.

She was later indicted and plead not guilty to fraud and conflict of interest charges.

Judge Frank W. Moskowitz ruled the charges be remanded because the state withheld evidence. 

For the case to go forward, the state will have to bring forward new evidence to a grand jury.

"It feels wonderful, it absolutely does," Smith told 3 TV/CBS 5. "I think truth has prevailed."

Smith was one of several top administrators, including the superintendent, who left the district last year amid investigations into procurement practices.
