 FILE - This undated file image provided by the Riverside County Sheriff's Department shows Norma Lopez, who has been missing since July 15, 2010, after failing to return from a summer school class. Exposed to the elements during the recent heat wave, the remains were so decomposed that authorities could not immediately determine the sex of the deceased, let alone whether it was Norma's body, said Riverside County Sheriff’s Department spokesman Sgt. Joseph Borja, at podium, confirms that a body was identified through dental records as Norma Lopez, during a news conference on Wednesday, July 21, 2010, in... (Associated Press) 
 
 An autopsy confirmed the identity of Norma Lopez, but investigators would not release the cause of death. Joseph Borja said. The discovery of the body was reported Tuesday just hours after Lopez's anguished family held a press conference to plead for her return, and authorities said they had no clues and announced a $35,000 reward for information leading to the arrest and conviction of whoever abducted her. Norma was reported missing about 12:30 p.m. Thursday by her older sister, Sonja, after she failed to return home from a summer biology class at Valley View High School. She was out of class by 10 a.m. and had plans to meet her older sister and a friend, authorities said. The body was found Tuesday afternoon by a local resident doing yard work in a remote section of town surrounded by wheat fields, just off the 60 Freeway.
– Remains found in a wheat field near a southern California town have been identified as those of a missing teenage girl police believe was abducted after a summer school program. Norma Lopez, 17, vanished a week ago after a biology class at Valley View High in Moreno Valley. Police have no suspects, but a green SUV was seen speeding from the spot where Lopez tried in vain to fight off her attacker, reports the Los Angeles Times. Investigators found some of Norma's belongings and signs of a struggle just blocks from the school. “We haven’t caught the suspect who killed Norma so obviously there is a murderer out there, so I would be vigilant, I would be aware," said Riverside County Sheriff Sgt. Joseph Barja. "If I were a parent I would keep track of my children. I would do everything to ensure their safety.”
