This was posted in comments by his sister on the last video he uploaded, ironically titled 'The End'.
Crissy_Mar10: I just wanted to share with all of Scotty’s fans that he passed away tonight from a heart attack I am his sister crissy. I don’t know how to inform most people so I thought I would share here. He talked about you all so much. He loved you guys and loved making videos for you. We miss him so much already. This feels like a nightmare. He was way too young. I didn’t want to make this post but this was his last post on here. We love you Scotty. We are devastated and miss you more than ever. I’m going to miss you so much. This is a nightmare and doesn’t feel real. I love you and I know everyone will miss you and everything you did for them.
I had the luxury of getting to speak with him a few years ago. He was smart as a whip and knew music. I accidentally “decoded” a message to a post and put it in the comments. Within 30 minutes I received direct messages which led to a couple conversations. I felt honored. TBH I'm still trying to figure out the rest of that message periodically. RIP Fren.
