Investigators: Shahzad left trail of clues
? Investigators say Faisal Shahzad left a long trail of clues for police.
One mistake officials say was leaving the hazard lights blinking on the SUV filled with explosives while parked in Times Square. Shahzad also left his keys in the ignition.
Officials say one of those keys found in the vehicle opened the door to Shahzad?s Connecticut home.
The most important clue left behind was the VIN number on the SUV?s engine.
All of the clues came together Monday when officials rushed to find Shahzad before he escaped on an Emirates Airlines flight.
