Two defendants who failed to appear last year in Forsyth County Superior Court on sex abuse charges remain on the lam, as is another man who disappeared in 2009 midway during his trial on child molestation charges. Karleen Chalker, spokeswoman for the Forsyth County Sheriff’s Office, said Friday that authorities are still looking for Charles Howard Bentley, Kenneth Dustin Grant and Marcus Tillman. Bentley, 72, of Bates Drive, failed to show up in September to enter a plea on two counts of child molestation.
