Police and Fire officials responded to the home and transferred her to UAB hospital for evaluation before being released. 

"I have been going nonstop since I received the call that she was missing on Thursday night," Russell’s boyfriend, Thomar Latrell Simmons wrote on Facebook. "I know she would’ve done the same for me, so I wasn’t going to give up until I saw her face again!"

Simmons said Russell was "fighting for her life for 48 hours, so until she’s physically and mentally stable again she is not able to give any updates or whereabouts on her kidnapper at this very moment."  

Russell's whereabouts were not immediately clear since around 10:45 p.m. Thursday when she called 911 and a family member to say she saw a young child walking on the side of Interstate 459.

Police found Russell's car and her cellphone but were unable to find her or a child in the area.

Hoover Police Lt. Daniel Lowe said the family member on the phone with Russell lost contact with her even though the line remained open. A single witness reported possibly seeing a gray vehicle and a man standing outside of Carlee's vehicle, but they had no additional information.

Talitha Russell told AL.com her daughter was headed home in the community about 10 miles south of Birmingham after leaving work and stopping to get food. She was on the phone with her brother's girlfriend when she said she saw a child on the roadside.

"My son's girlfriend heard her asking the child, 'Are you Ok?' She never heard the child say anything but then she heard our daughter scream,'' Talitha Russell said. "From there, all you hear on her phone is background noise from the interstate."

During the search there were two separate rewards of $20,000 and $5,000 for information assisting Russell's safe return, police said.
