Maybe he was scared thinking the killer was still around. Maybe he didn't know it was a dump job & the killer could still be in the area.
He explained he had a small child and apologized for losing his composure when he saw her body.
IMHO no one knows how they will react to such a horrific sight as a child , dead and tossed aside the road like trash.....
I felt sorry for the guy myself.........
Stay Safe !
