So if this man did leave the suitcase, it probably wasn't when the 2 women out walking saw him, but later in the day around lunchtime... because that's when he was seen again with the suitcase.
It wouldn't take 4+ hours to walk 2km with a suitcase, He was seen close to Wynarka around 7-8am and again west of Wynarka around lunchtime and the suitcase was located 2km from Wynarka. What I gather is that he was walking around with the case for half a day or most of the day, maybe trying to find a suitable spot for it????
