A missing south Charlotte mother and her 8-year-old daughter have been found after disappearing for over 24 hours.

According to Charlotte-Mecklenburg Police, Megan Stack and her daughter, Ava, went to an emergency medical service station outside St. Louis Wednesday morning and asked to be taken to a hospital to be evaluated.

Authorities are working to reunite Ava with other family members.

Megan picked Ava up from class at Bain Elementary School Monday and the two disappeared, prompting officials to launch a Silver Alert and request an Amber Alert (which was denied).

“Because of Megan Stack’s emotional state and recent behavior, there is serious concern for their safety,” CMPD said. While officials would not specify the nature of the concerning behavior or any medical issues, they said she has had concerning behaviors in the past.

Ava's father, Timothy Lieberger, also addressed media Wednesday pleading for any information on his daughter's whereabouts.

“She’s my world. She’s everything to me. She’s all I have. She’s missing," Lieberger said.
