A 15-year-old high school freshman from the City Heights area of San Diego went missing last week from Crawford High School, and her family issued a plea Sunday for the public’s help locating her.

Daisy Campos was last seen on Nov. 5 wearing black shorts, white Adidas shoes and an Oceanside High School sweater with “Campos” and the number 61 on the back, according to her mother, Angelica Parkinson. Daisy also has a scar over her left eye and scars on her arms and legs from self-harm, her mother said.

The family has hired Glendale-based private investigator Moses Castillo, a former LAPD sex crimes detective, to help locate Daisy.

“We are concerned that she was lured by an individual on social media,” Castillo said. “Oftentimes teenagers get tricked, lured and our concern is that this could lead to human trafficking.”

Daisy’s mother said that prior to her disappearance, the teen was communicating with someone on Instagram purporting to be a 16-year-old boy in Baton Rouge, Louisiana, and that her daughter was making plans to travel to see him.

“Its very stressful to not know if she’s OK, or cold, or if she has eaten, or is living outside,” Parkinson told City News Service. “It’s hurtful and stressful and we just want her to come home.”

Parkinson fears Daisy may have taken a cross-country bus or possibly is hitch-hiking to Louisiana.

Last Thursday, the San Diego Police Department was notified that Daisy had been missing since the day before, the department confirmed to NBC 7 on Monday.

“She was last seen at Crawford High School between 1-1:30 p.m. The Department’s Community Youth Services is currently investigating her whereabouts,” SDPD said.

Parkinson said her daughter was not carrying any identification, had no credit cards and only about $10 or $20, but she did have a local transit pass that she might have used after leaving Crawford before classes let out for the day. School officials also have been looking into Daisy’s disappearance.

Parkinson says there is evidence that Daisy is still in communication with her friends and that she is telling them not to tell the family her whereabouts.

“She’s going by the name Emily now, telling others that she was kicked out, that we don’t want her, and we believe she’s crazy and want to send her to a crazy house’,” Parkinson said.

Daisy has a history of anxiety and depression and has been seeing a therapist and school counselors, according to Parkinson.

“We want to help her, not send her away,” she said.

Anyone with information about Daisy was asked to call 911, San Diego police at 619-531-2000, or the National Center for Missing & Exploited Children at 800-843-5678.
