Police investigating Carlee Russell disappearance haven't found evidence of toddler on Alabama highway

Police are continuing to build a timeline of Carlethia "Carlee" Nichole Russell's whereabouts after the 25-year-old vanished Thursday night after calling 911 to report spotting a toddler on an interstate in Alabama. Russell returned home two days later as the incident gained national attention.

Russell vanished after she called 911 in regards to a toddler in a diaper walking along the side of a highway, authorities say. She returned home Saturday night, but in the days since, investigators have not found any evidence of a child on the highway, the Hoover Police Department said Wednesday. The department never received any other 911 calls about a toddler on Interstate 459, even though multiple vehicles passed through the area on Thursday night. 

"Numerous evidentiary items are still being evaluated, and those items are key in the process of determining exactly what took place in the approximately 49 hours Carlee was missing, but also what took place prior to her disappearance," police said in a social media post Wednesday.
