Dublin Police Services is investigating the December 6, 2011 incident involving an errant cannonball that struck at two homes and damaged a vehicle in the City of Dublin. The television show “Mythbusters” was filming an episode at the Alameda County Sheriff’s Office Regional Training Center at the time. Representatives of the “Mythbusters” program and the Alameda County Sheriff’s Office are cooperating with the investigation. The City does not have jurisdictional oversight of activities that occur at the County’s Training Center, but City Manager Joni Pattillo has been in contact with the Sheriff’s Office to discuss the incident. Sheriff Greg Ahern has advised the City that he has suspended all non-emergency activities at the Sheriff’s Bomb Disposal Range until the completion of a full investigation into this incident.
