PIERRE, S.D. -

The South Dakota State Supreme Court has affirmed the murder conviction and sentence for Maricela Diaz, who killed 16-year-old Jasmine Guevara on Nov. 10, 2009.

According to Attorney General Marty Jackley, Diaz is to serve 80 years in prison for the first-degree murder conviction and 50 years for felony murder kidnapping. The two sentences are to be served concurrently. Diaz was convicted in Jan. 15, 2015 by a Minnehaha County jury.

Jackley says Diaz along with Alexander Salgado lured Guevara to a location in rural Hanson County where they stabbed her, cut her throat and shoved her into the trunk of her own car and then set it on fire while she was alive inside.

Salgado plead guilty to second-degree murder in August 2010. He is currently serving a life sentence.
