In December, Daniel Holtzclaw, 29, was found guilty on 18 of 36 charges of sexual assault, including rape. The judge handed down the sentence after victims said the former officer had destroyed their lives.
Prosecutors said Holtzclaw preyed on women who had trouble with the law and forced them into sex under threat of arrest, hoping their word would not hold up against his in court.
Holtzclaw sexually abused multiple women between December 2013 and June 2014, targeting African-American women while he patrolled a poorer area of Oklahoma City.
Thirteen women testified against the former officer at his trial last year, saying he forced them to perform sexual acts on him.
Holtzclaw, who did not testify at his trial, was fired over the accusations in January 2015, about five months after charges were brought against him and after approximately three years on the job.
