A South Carolina couple has been arrested in connection with a grisly cold-case murder of a 19-year-old college student, whose body was found in a culvert in rural Kansas in 2010. The Butler County Sheriff’s Office on Tuesday announced the arrests of Kristopher Valadez and Candace Valadez, both 32, in Simpsonville, South Carolina, in the killing of German Clerici. According to the law enforcement agency, in early February 2010, Clerici’s mother reported the college student missing after not hearing from him in several days.
