Officials said he “befriended” the girl while investigating her case and sexually assaulted her. When he was arrested in November, Kimball was accused of tying up and raping the girl during an incident in Camarillo in 2017.

Kimball will also have to register as a sexual offender as a part of the plea deal. He was also ordered to pay the victim $50,000 for “her pain and suffering” and a no-contact order was issued.
