ABILENE, Kan. (AP) – Dickinson County authorities say laboratory tests found no evidence to indicate how an Abilene man died.

The skeletal remains of 42-year-old Jason Southern were found northwest of Abilene in March 2015. He had been reported missing in July 2014.

The Salina Journal reports Southern worked as a forklift operated for Russell Stover Candies.

Dickinson County Sheriff Gareth Hoffman says the remains were tested by the Kansas Bureau of Investigation laboratory in Great Bend. He says officers will continue to investigate the death.
