You are awesome--thank you! I found it! I kept thinking he was wearing a different color shirt and never even clicked on this one in my mad dash to find the video.
@LadyL, here is the video of Bryer's dad talking about Bryer always being at Kam's place and not the other way around. Between this and the video interview I already posted with the uncle (who confirms he never met Kam despite him being a good friend of Bryer's) and the article I previously posted with Bryer's grandma's neighbor saying she never met Kam except through his work at Wal-Mart, despite Bryer being a really close friend of her son's, I think it's pretty clear that Bryer didn't want Kam around his family.
