On 6^th August 2011, 23-year old student Dalene Carlson vanishes from Stockton, California.  She’s only been in town a couple of weeks, when she arranges to meet some new friends in a local bar.  But what happens next is a mystery.  CCTV footage from the bar shows her talking to a number of young men, each of which is a potential suspect.  But investigators are in the dark as to what happened once the bar closed - until surveillance footage from a liquor store shows her late-night shopping with a mystery man.  When they track the suspect’s journey, they uncover more footage revealing strange and deeply suspicious behavior.  But can investigators prove that he holds the answer to the question ‘What happened to Dalene Carlson?’
