As far as "disturbing" goes, according to the eyewitness accounts, and the time stamp on his phone, the witness called 911 to report Haskins in the middle of a lane, and that was at 6:31
The accident occurred at 6:37.
Based on that information, he was wandering on the road at least a full 6 minutes before being struck. Maybe even longer
Putting yourself in that position for 6 minutes seems kind of disturbing.
Plus, factor in whatever amount of time it took the witness, to make the decision to call, and then get his phone and call 911, from the time he witnessed that.
