Step-grandmother of teen cruise murder suspect speaks out in CBS interview

The step-grandmother of a teenager charged with murder and sexual abuse aboard a Carnival cruise ship is publicly calling for criminal charges against the adults she says were responsible for watching the kids. Sonya Ziske, speaking exclusively to CBS News, is demanding charges against Chris and Shauntel Kepner — the family members she says were responsible for supervising the teens on board the ship. Her step-grandson, Timothy Hudson, 16, faces federal charges of first-degree murder and aggravated sexual abuse in the death of his stepsister, Anna Kepner. A federal judge has allowed Hudson to remain free while the case continues.
