The family of a missing 15-year-old Las Vegas girl is desperately searching for her after she vanished on May 18.

The Las Vegas Review-Journal reports that Molly Reyes, a Bonanza High School freshman, went missing after attending a practice for her upcoming quinceanera at Firefighters Memorial Park at Torrey Pines Drive and West Oakey Boulevard.

Molly reportedly told her friends that her father would be picking her up that day, but when he arrived on schedule at 6 p.m. the teen was nowhere to be seen.

“We haven’t seen or heard from her since,” Molly’s older sister Sasha Reyes told the newspaper.

“We have high, high hopes that she’ll be back,” Sasha said.

It is unclear if Molly is considered a runaway. The family has been working to spread the word about her disappearance, posting missing persons flyers in the area and searching “night and day,” the Las Vegas Review Journal Reports. The family has also contacted the Metropolitan Police Department’s missing persons bureau and the Center for Missing and Exploited Children.

Molly is 15 years old, 5 feet, 5 inches tall and weighs 137 pounds. She has black hair and brown eyes and was wearing pink pants and a white shirt when she was last seen.

Anybody with information on Molly’s whereabouts is urged to call Metro at 702-828-2907 or 702-828-3111.
