Harrisonville teen Reyes Olivas was sentenced April 2 to two life sentences in connection with the January 2010 murder of his 14-year-old cousin, Katie Rios in the home they shared with the victims parents south of town.
Cass County Presiding Circuit Judge Jacqueline Cook sentenced Olivas to life without the possibility of parole for his first degree murder conviction, and life for his conviction on a second charge of armed criminal action.
He was found guilty in Cass County Circuit Court of both charges following a two-day trial in February.
Defense attorney Nate Anderson told the jury during the trial that Olivas did, in fact, stab Rios to death on a bitterly cold January day when both were at home on their own. A winter storm had closed schools for the day.
However, he argued, the act was not premeditated.
Prosecutors argued he had taken time to prepare a large duffel bag with possessions and supplies before committing the act and leaving the house, and witnesses testified that he had often complained about his younger cousin, calling her spoiled and other names.
