On October 15, 2015, 16-year-old Arely Arzate-Lujan was shot to death at a residence in North Las Vegas, Nevada. Detectives say she was with her boyfriend, 16-year-old Casey Olaf Sandoval, who allegedly shot her with a handgun and then attempted to hide the weapon after the shooting.

Sandoval was arrested and charged with one count of murder; his arrest was announced on October 19, 2015. Investigators cited the attempt to conceal the firearm as a significant piece of evidence in the case, and Sandoval was later indicted to face trial on the charge.

Arely’s death prompted a criminal investigation and a formal prosecution for homicide. If anyone knew Arely, Sandoval, or has information about what happened at the residence that night, please share what you know.
