Federal investigators say they are seeking the cell phone records of two teenagers and the deceased engineer of a commuter train involved in a collision with a freight train on Friday. The accident has left 25 dead and more than 130 passengers injured. The teens, who are train enthusiasts, came forward to say that they had been texting the engineer prior to the collision. "We have been in contact with them and their families. They have been fully cooperative," Kitty Higgins of the National Transportation Safety Board told reporters. "We are going to be obtaining records from their cell phones and of the deceased ... to begin to determine what might have happened and what if any role [cell phones] might have played in this accident." No cell phone was found on or near the dead engineer. CNN Story here.
