DENVER, Colorado (KCNC) A serial rapist in Colorado is headed to prison for the rest of his life and then some.

A Jefferson County judge sentenced Marc O'Leary to 327.5 years in prison.

O'Leary pled guilty to 28 counts for sexually assaulting three women in Golden and Westminster and an attempted rape in Aurora.

O'Leary says, "I can only hope that my sentence today will satisfy them... as far as closure is concerned and moving on with their lives."

Prosecutors described the attacks as four hours of torture.

O'Leary also faces rape charges in Washington State. He pled guilty to those as well.
