DNA from mystery juvenile male raises questions in Carnival cruise murder case against teen stepbrother

Federal investigators obtained DNA from a mystery juvenile male allegedly involved in sexual activity with 18-year-old Anna Kepner aboard a Carnival cruise ship before her death, complicating the case against her stepbrother Timothy Hudson, who faces charges for her alleged sexual assault and murder. DNA evidence from Kepner's body strongly suggests Hudson as the contributor, but prosecutors confirmed the other minor is not Hudson.
