HARRISONVILLE, Mo. - A Cass County jury determined Thursday that a man who killed a teenage girl in 2010 in her Harrisonville home is guilty of murder in the first degree and armed criminal action.

Reyes E. Olivas, who was 16 when the crime occurred, was tried as an adult for killing Katie Rios, 14 .

Rios' parents found her dead inside her home on South Hess Road south of Harrisonville on Jan. 7, 2010.
