ORLANDO, Fla. - Lindsay Louise Ellixson was far away from home when she was murdered in east Baton Rouge, La., reportedly trying to explore the world.

Ellixson graduated Boone High School in 2011, was part of the swim team, and made her way to Louisiana after finishing high school, officials said.

She vanished earlier this month, investigators said.

Homicide detectives discovered her body in a bayou with blunt force trauma to her head, neck and chest.

Authorities called her murder "unusually brutal and violent."

The perpetrator is still on the loose, officials said.

Local authorities, state police and the FBI are investigating the crime.
