Info on death of GregoryWard struck&Killed@North Picayune Exit onI59 I8Wh hit&run

This is the stretch of highway where his body was found,between Exit 6 and Exit 10.
I’m surprised that there isn’t any surveillance camera footage,either from MDOT or possible outside sources (nearby retail stores,shopping centers or other municipal jurisdictions,etc.) that could have possibly caught what happened!
Not much to go on.
