The man who sparked creation of Mothers Against Drunk Driving when his car killed a 13-year-old girl five years ago has been ordered held without bail in Sacramento on his sixth drunk driving charge. Clarence Busch, 52, who had been held in lieu of $200,000 bail, was charged with being drunk when he made an illegal left turn April 17 and struck a car driven by a 19-year-old girl, who suffered minor injuries. “All I can do is look at past conduct because there is no way to gauge future behavior,” Municipal Judge John Stroud said, invoking a provision of the state Constitution allowing a judge to refuse bail when there is a threat that an act of violence will recur. Prosecutor Dave Hall said Busch had a blood alcohol level of 0.20%, twice the presumptive limit for legal intoxication. A preliminary hearing is scheduled for next Monday. Candy Lightner founded MADD, a nationwide lobbying group, soon after her daughter was killed in 1980.
