Carlee Russell searched if Amber Alerts cost money and the plot of the movie 'Taken' before her strange disappearance, police say

• Carlee Russell searched the cost of Amber Alerts and the "Taken" movie before her disappearance.
• Russell called 911 reporting a toddler on the highway before she went missing on Thursday and reappeared Saturday.

In the days before her disappearance, Carlethia "Carlee" Nichole Russell searched the cost of an Amber Alert and the plot of the movie "Taken," Hoover police said.

On Wednesday, Hoover Police Department told reporters they'd been looking into the timeline from when Russell went missing last Thursday to her reappearance at home on Saturday.

During their investigation, police said they discovered Russell had searched whether or not an Amber Alert costs money, as well as the maximum age for an Amber Alert.

Russell also looked up the Liam Neeson movie "Taken," researched how to take money from a register without being caught, and looked into the Birmingham, Alabama, bus station and one-way bus tickets, police said.

Russell, 25, vanished after calling 911 to report seeing a toddler on a highway in Alabama.

She returned home approximately 49 hours later, with her case receiving national media and social media coverage over the weekend.

But police haven't been able to verify most of the initial statements Russell told investigators, and Hoover Police Department Chief Nicholas Derzis said authorities have "have no reason to believe that there is a threat to the public safety related to this particular case."

On Wednesday, the police department posted on Facebook: "The Hoover Police Department has not located any evidence of a toddler walking down the interstate, nor did we receive any additional calls about a toddler walking down the interstate, despite numerous vehicles passing through that area as depicted by the traffic camera surveillance video."

Police also said they'd reached out for another interview with Russell, but didn't agree to the request.
