The Truth Reconciliation and Justice Commission completed the report Thursday, but it has not yet been released because it has not been presented to President Uhuru Kenyatta, the BBC reported.
The commission began the investigation into allegations of violent human rights abuse in Kenya five years ago following the country's violent 2007 presidential election, during which 1,500 people were killed and more than 300,000 forced to flee their homes.
The investigation looked at past injustices dating to Kenya's independence in 1963.
Ahmed Sheik Farah of the commission said until the report is officially released, he cannot say what it recommends, but said victims of violence in Kenya will be satisfied.
"It was a victim-centered process, so I think that the victims will be happy with this," Farah said. "Some will [face prosecution], we have recommended some people for that, but remember also that we have been centered on reconciliation -- healing, unity that kind of focus."
