A suspected serial killer has been charged with the murders of three women in Southern California nearly 50 years ago. Kimberly Fritz, 18, Velvet Sanchez, 31, and Lorraine Rodriguez, 21, were all strangled to death in 1977, but investigators ran out of leads at the time. “While believing these three crimes were indeed connected, leads ran cold, and detectives were unable to identify who was responsible for these horrific murders,” Ventura County District Attorney Erik Nasarenko said at a press conference this week.Warren Luther Alexander of Diamondhead, Mississippi, who worked as a long-haul truck driver at the time, was linked to the murders when his DNA matched the crime scenes after being uploaded to the Combined DNA Index System (CODIS), a national database, last year. TEXAS MAN ARRESTED IN 1982 COLD CASE MURDERS OF MOTHER, YOUNG DAUGHTER DIES BEFORE TRIAL A suspected serial killer has been charged with the murders of three women in Southern California nearly 50 years ago.  (Ventura County District Attorney’s Office)Alexander was extradited from North Carolina Tuesday, where he was in custody and charged with a murder there in 1992. The California victims were all murdered between the end of May 1977 and December 1977. “These murders may have occurred 47 years ago, but the investigators with the Ventura County DA’s office, the investigators with the Ventura County Sheriff’s Department Cold Case Unit, officers and detectives with Port Hueneme and Oxnard never gave up.
