Brevard County Teen's Cruise Ship Death Ruled A Homicide

(Tallahassee, FL) -- Details are out on the death of a Brevard County teenager on a cruise ship. Anna Kepner's death certificate was issued yesterday. It shows the 18-year-old was strangled to death, and there were no signs of sexual assault, drugs or alcohol. She was found dead three weeks ago on a cruise ship after it docked at Port Miami. Family members say Kepner's 16-year-old step-brother is a suspect, but no charges have been filed. Anna's grandmother tells ABC News that Anna and her step-brother were two peas in a pod and just like brother and sister.
