PHOENIX (AP) -- A judge has sentenced a former sailor involved in a love triangle with his former teacher to 10 years in prison in the stabbing death of an 18-year-old man.

Maricopa County Superior Court Judge Christopher Whitten sentenced 21-year-old Sixto Balbuena on Friday stemming for his second-degree murder.

Balbuena killed Samuel Valdivia when he found him at the Chandler home of 49-year-old Tamara Hofmann, who was his supposed fiancee. The two had begun dating when Balbuena was Hofmann's student at Tempe's Marcos de Niza High School.

Police reports show Balbuena found Hofmann naked and Valdivia wearing only boxer shorts when he arrived at her home on April 9, 2009.

After several hours of police questioning, Balbuena admitted he flew into a rage and killed Valdivia.
