LAS VEGAS (AP) - Police are seeking two people for questioning in the slaying of a Las Vegas high school student found shot to death in a storm drain.

They're not calling them suspects, but police say they think the two men in their early 20s were involved in an altercation with 17-year-old Joseph Lopez shortly before his body was found Monday evening in a tunnel beneath Tropicana Avenue near the 215 Beltway.

Officials say Lopez was a junior at Spring Valley High School.
