We at work speculated because details were really quiet for a while that maybe it was a suicide? But he did have an absolute ton to live for (NFL QB, gorgeous wife or girlfriend etc) so that doesn't necessarily make sense, either.. just a very odd thing to have happened and we've been trying to piece it together, ourselves.. He clearly had a cell phone - why not call for help and sit in the car and wait for it..?
