ALYSSA Otremba was just minutes from home.
She had just been at a friend's house to borrow a geometry textbook top help with her studies. As she left for the short trip back home in northwest Las Vegas she couldn't imagine the horror awaiting her.
She never made it home.
Just 90 metres from her front door, the 15-year-old was attacked by Javier Righetti.
The Las Vegas Review-Journal reports Righetti, 19, had stalked the young girl almost a kilometre before he raped and killed her in a tunnel in September 2011.
He confessed to police he stabbed the young teen in the face and body 80 times. He then carved initials "LV" into her lifeless body, which he later burned.
The Review-Journal reports Alyssa had just finished her first week as a freshman in high school. It was Friday night and she played with the marching band at the school's football game.
She took the day off school because she was sick, so had to pick up the geometry textbook from her friend that evening.
According to the Review-Journal, her mother warned the teen not to walk on her own but Alyssa wanted to get her homework done so she didn't have to worry about it on the weekend.
It's been six years since that fateful day and Righetti who had previously been found guilty was this week sentenced to death for the crime.
The Review-Journal reports that a month before he attacked Alyssa, a warrant was out for his arrest over the rape of his cousin.
Righetti is now the youngest man in Nevada state on death row at the age of 24.
He admitted to raping two other girls in the same tunnel where he raped Alyssa, right near her home.
"We're grateful justice has finally been done," Alyssa's mother Jennifer Otremba told reporters.
"In all honesty, this is not a win for anybody.
"This journey's been hard and it's just beginning for us, as well. We have the rest of life to live without Alyssa."
