Norma attended a summer class between 8 a.m. and 10 a.m. at Valley View High School, which is only one mile away from her house on the 27000 block of Cottonwood Ave.
She had planned to meet her younger sister and a friend at about 10 a.m. at her house, but police said the teen never arrived.
Riverside County Sheriff's Sgt. Joe Borja said Norma usually took a shortcut home when walking home from school, according to her family.
When she did not arrive home, her family searched for her for two hours. During that search, Borja said, they found personal items of hers that indicated a possible struggle. Detectives said Norma may have been taken against her will. Authorities did not want to reveal the contents of those belongings, citing the ongoing investigation.
A newer model green-colored SUV was seen in the area of Norma's disappearance. Borja said the SUV was not considered a suspect vehicle, but that they do want to interview the driver in hopes of learning additional information about the circumstances of Norma's disappearance.
Officers talked to local business owners and searched the hillsides around the Cottonwood Avenue address, but found no sign of her.
Norma is about 5 feet, 7 inches tall and weighs about 110 pounds. She was last seen wearing a black-and-white horizontal-striped sleeveless shirt and black jeans.
The FBI and the National Center for Missing and Exploited Children joined the Moreno Valley Police Dept. in the investigation.
