Police are searching for a 25-year-old woman after she disappeared when she stopped to look for a child she saw walking along an Alabama interstate highway.

Carlethia “Carlee” Nichole Russell called 911 about 9:30 p.m. on Thursday night in Hoover, Alabama, and reported seeing a toddler walking along the side of the interstate. After calling 911, Russell stopped to check on the toddler and also called a family member to tell them about the situation.

The family member lost contact with her, but the line remained open. Officers who were already en route to the location of the initial 911 call located the Carlee’s vehicle and some of her belongings nearby, but were unable to find her or a child in the area.

Police said they had not gotten any other calls about a missing child.

Russell was last seen wearing a black shirt, black pants and white Nike brand shoes. She is 5 feet, 4 inches tall and weighs 150-160 pounds.

Russell was traveling home from work in Birmingham, Alabama, and is believed to have picked up food on her way back before heading toward Hoover on I-459. She stopped to look for the child “near mile marker 11 between the Galleria flyover and Exit 10 for Highway 150.

In a press conference Friday, Hoover Police Department Lieutenant Daniel Lowe said they are looking into all possibilities regarding the situation.

Lowe said the police department is receiving “a lot” of tips and are assigning investigators to them as they come in. Any person with any information is asked to contact Detective Brad Fountain at 205-444-7562, Sergeant Drew Mims at 205-739-7274, or Crimestoppers of Metro Alabama at 205-254-7777 if they wish to remain anonymous.

Additionally, an anonymous donor offered $20,000 for Russell’s return, and Crimestoppers is also offering an additional $5,000.
