The Pennsylvania attorney general's office released the results of its review of the Jerry Sandusky investigation Monday, per the Associated Press.
The report found that law enforcement and prosecutors had unnecessarily extended the case with "crucial missteps and inexplicable delays," but that those errors had not been politically motivated.
Authorities first received complaints regarding Sandusky, the former Penn State defensive coordinator, in late 2008. He was arrested in 2011, nearly three years after the initial complaints, then convicted on 45 criminal counts of sexual abuse of 10 boys over 15 years in summer 2012.
Attorney General Kathleen Kane promised the review during her campaign for the office in 2012, suggesting that then-attorney general and now-Pennsylvania governor Tim Corbett slowed the investigation into Sandusky over political motivations. Kane is a Democrat, and Corbett a Republican currently seeking another term in the governor's office.
Corbett denied Kane's accusation, pointing to the necessary thoroughness of the investigation and its eventual success in earning a conviction.
The report -- overseen by a former federal prosecutor and current law school professor hired by Kane -- blamed the delays on Sandusky's arrest and charges on "communication problems," according to the AP.
Sandusky is currently serving his 30-to-60-year sentence in Pennsylvania's Greene State Prison.
