Man Charged in 2017 Simi Valley ‘Scream’ Mask Attack

Releasing new photos, officials hope public tips will identify other members of the masked group and move the investigation forward.

Overview

  • Ventura County prosecutors identified and arrested Ricardo Jimenez-Garcia and filed charges related to the attack after renewed casework led to his detention on Sept. 9, 2026.
  • The original assault happened on Sept. 21, 2017, when a woman walking to work along Galena Avenue was attacked by a group of men wearing ‘Scream’ masks and threatened with a knife before the suspects fled.
  • Officials say charges have been filed against Jimenez-Garcia but they have not publicly disclosed the specific counts or the precise evidence that linked him to the case.
  • On Oct. 23, 2026 authorities released new photos of the suspects and asked anyone who witnessed the attack or recognizes the men to call District Attorney Investigator Yumi Kirk at (805) 477-1638.
  • The probe remains active with other participants not publicly identified, and investigators say tips could lead to more arrests, help confirm whether there are additional victims, and provide closure for the woman attacked.
