DALY CITY, Calif. (KTVU) -- Family and police are asking for the public's help finding a 16-year-old Daly City girl with mental disabilities who has been missing since Sunday night.
Police say detectives have put out missing person flyers with photos of Destiny Peoples at places she's known to frequent.
"She can appear to be her 16-year-old age, but mentally she's not 16," said Loraetta Peoples, Destiny's grandmother.
Relatives say they last saw the teenager Sunday night around 7:30 p.m. when she left the home she shares with them.
Peoples said her granddaughter faces challenges; she has the mental capacity of a child and needs medication.
Relatives said Destiny frequently goes to Serramonte Mall near their home. On Sunday afternoon, Destiny was found at the parking lot of a fast food restaurant on Gellert Boulevard near her home.
Someone at the business called police and officers took her home, but she left again.
"We just want to get her back home so that she can get her medication and try to get her some help," said Peoples.
Family members say Destiny is troubled by a desire for a relationship with her biological mother who is unresponsive.
Peoples told KTVU the teen recently connected with a man online who friended her on Facebook.
"That's the scary part about it, is that she would go with someone that could potentially hurt her," said Peoples.
Destiny's twin brother Dashon Peoples says they have a close relationship and hopes his sister can hear his plea.
"Destiny, please come back because it's dangerous outside at night. The family is missing you," said Dashon.
Police say they are treating this case as a missing juvenile at risk.
Destiny doesn't have a cell phone. Her family is urging anyone who sees her to call police.
