Gary, Indiana (CNN) -- The man accused in a string of killings in Indiana appeared in court for the first time Wednesday but was held in contempt after he refused to answer the judge's questions, forcing the hearing to be rescheduled for next week, CNN's Poppy Harlow reported. Darren Deon Vann has been charged in the death of 19-year-old Afrikka Hardy, and authorities say he has confessed to killing six other women and led police to their bodies. On Wednesday afternoon, Lake County prosecutors also charged Vann in the death of a second woman, Anith Jones. Vann faces three counts related to Jones, including murder, murder in the perpetration of a robbery and robbery resulting in serious bodily injury, according to court documents.
