A Las Vegas 19-year-old pleaded not guilty to the kidnapping, rape and mutilation killing of a high school sophomore in his first court appearance since prosecutors announced they'll seek to have him put to death if he's convicted.
Javier (HAH'-vee-air) Righetti appeared in court Thursday in Las Vegas with his wrists and ankles shackled. His trial is set for next Oct. 16.
Righetti is charged with the deadly attack on 15-year-old Alyssa Otremba in September, and with assaulting another teenage girl in March.
Otremba's mother, Jennifer Otremba, declined to speak about the case outside the courtroom but said she wanted justice for her daughter.
Alyssa Otremba's charred body was found Sept. 3 not far from her northwest Las Vegas home.
Prosecutors allege she was stabbed more than 80 times.
