Student killed in love triangle with maths teacher
Chandler police said Sixto Balbuena, 20, told them he never meant to kill Samuel Valdivia. He allegedly told police “the blade went in like going into butter” and that he just wanted to show Valdivia how much he had hurt him by sleeping with Tamara Hofmann.
Balbuena, a navy sailor on leave from California, was arrested on a charge of second-degree murder after police found him covered in blood and he told them about the killing.
