VICTIM:          Confidential female



On July 5, 2018, at approximately 3:00 a.m., the victim arrived home and was waiting to exit a friend’s vehicle when John Contreras was observed exiting a vehicle parked behind them wearing only a tank top and underwear.  Contreras carefully avoided activating the motion sensored lights in the front of the residence and went directly to the victims bedroom window where he began looking into the window from multiple angles.  Contreras became aware he was being watched and quickly hid behind a palm tree before running back to his vehicle and fleeing.  Witnesses were able to obtain Contreras’ vehicle information, and while reporting this incident, the victim alerted deputies to additional incidents involving Contreras being at her residence.  Contreras is not known to the victim.

Further investigation revealed Contreras is a registered sex offender, registered in the City of Montclair.  After multiple attempted contacts, Contreras was finally taken into custody by deputies on July 10, 2018 at 9:24 p.m.
