Prosecutors turned over some of the records, but withheld a computer presentation and documents used to review the evidence.
Brittney Angel tried to get the records after she was charged in Colorado Springs with eluding, evidence tampering and concealing a death in 2011.
Her attorneys wanted to find out if there was any police misconduct.
Angel wanted to know why the district attorney cleared a deputy sheriff who killed another woman outside a motel after the woman moved her car toward the deputy.
Angel was accused of jumping into the driver's seat and fleeing.
