HAYS (AP) – Ellis County authorities say the death of an 18-year-old Hays high school student was accidental.

The body of Citlatli Adilene Armendariz was found Monday afternoon in a creek about a mile south of Hays. She had been missing since she left a party Saturday night.

KWCH-TV says a coroner’s report found she died of hypothermia along with head injuries resulting from a fall.

The Ellis County sheriff’s office says Armendariz fell down a 6-foot embankment and landed head first on ice in Big Creek. She then walked about another quarter mile to where her body was found.

Investigators say there is no indication of foul play, though the investigation will continue.
