A timeline of the Carlee Russell case: What happened to the Alabama woman who went missing for 2 days?

Police investigators in Hoover, Alabama, have put together a timeline of the roughly 50 hours during which Carlethia "Carlee" Nichole Russell, a 25-year-old nursing student, was missing after she called 911 last week from the side of a highway. 

"We pretty much know exactly what took place from the time she left work until the 911 call," Hoover Police Chief Nick Derzis said at a news conference Wednesday.

Russell briefly recounted her ordeal to investigators after she returned home on the night of Saturday, July 15, two days after being reported missing.
