Connecticut State Police are now focused on a 2010 Camaro that tried to merge onto the interstate.
They've concluded that the Chevy, driven by a Stamford man, hit a gasoline tanker truck -- the tanker then crashing into a tractor trailer and then bursting into flames under the Fairfield Avenue overpass -- the bridge dismantling and road repairs becoming a multi-day project.
Though they've narrowed down the cause, no one has been charged, but the investigation continues into the crash, from which, somehow, all three drivers were able to walk away.
