Police in Southern California are questioning sex offenders who live in the area where Norma Lopez was abducted and murdered, as the hunt for her killer expands.
The 17-year-old girl's body was found Tuesday, five days after she disappeared while walking home from summer school in Moreno Valley, east of Los Angeles.
Police have set up road blocks outside Norma's school, questioning drivers in the hopes of finding someone who may have seen Norma leave school last Thursday and might have seen something that leads to her killer.
Investigators have also began contacting 14 registered sex offenders listed on the Megan's Law website who live within a 2-mile radius of where Norma was last seen.
Police are still looking for the driver of a green SUV seen speeding from the area the day Norma vanished. That person is not considered a suspect, rather a possible witness.
Authorities have declined to release her cause of death, citing the ongoing investigation, and would not say if she was sexually assaulted. Her decomposed body was identified using dental records.
Norma's best friend, Giovanna Gutierrez, said she was supposed to meet Norma at the high school for senior class pictures the day she disappeared.
"She didn't have any problems. She was always full of laughter," Gutierrez said.
