The family of a teenage girl from the Bronx is asking for the public's help finding their missing daughter.

They say 17-year-old Dora Lespier went missing after she walked out of a treatment center in Westchester County on Dec. 5.

The family says she was getting treatment for bi-polar and schizophrenia at Linden Hill Residential in Hawthorne and is believed to be headed to the Simpson Street station in the Bronx. Her family says they think she came back to the Bronx to meet up with her 23-year-old boyfriend. 

Fliers have been put up, her family says, in hope someone knows where she is.

Anyone with information is asked to contact Mount Pleasant police at 914-769-1941.
