ST. LOUIS -- A mother and daughter from Charlotte who were missing for 36 hours have been located.         

Megan Stack and her 8-year-old daughter, Ava, were found Wednesday morning safe in Missouri.

They went missing on Monday after police say Megan picked up Ava from school.

Charlotte-Mecklenburg police say Megan checked into an EMS substation in St. Louis to get help.

She is receiving a medical evaluation.

Police were concerned about the disappearance because of some troubling conversations Megan had recently had with family members.

Ava will return home to Charlotte to be with family.

Police say there are no plans for charges to be filed.
