That is definitely Mark and definitely Jr.
They both wore hats during the day but Mark would where a hat constantly , not that that hats have any thing to add but that’s how they looked everyday .
Jr. looks around 16-17 and Marks picture has been around for years and shown in a couple papers if not more. I think they were taken around the time they were both having trouble in High School obviously a couple years apart.
Jr. may be a little older than 16-17 in that photo. Looks like he has a beard unless that's the lighting.
