One man was killed and four injured after driving off a cliff in South Monterey County over the weekend. Officials say the men were off-roading at Williams Hill Recreation Area near Lockwood early Saturday morning when they lost control of the vehicle and rolled 700 feet down an embankment. All five were ejected from the vehicle. The driver, 24-year-old Andrew Kruep of Orinda, was pronounced dead at the scene. The passengers, one man from Lafayette and three men from San Luis Obispo, were transported to the hospital with severe head injuries. The incident is under investigation.
