Austin Harrouff, the 19-year-old Florida State University student who is accused of fatally stabbing a couple in their southern Martin County home, had begun building a library of YouTube clips within the last few months..

The clips, on a video channel named “A. Frost”, show Harrouff’s interests in music and bodybuilding.

His bodybuilding clips centered around him discussing his philosophies and how he lost weight in the last few months. He occasionally slips into fake accents during these videos.

His music clips touch on a variety of styles — he calls one playlist “Make Trap Great Again”, where he uses the names AustiFrosti or simply Frosti, delves into trap music, which is a cross between hip-hop and electronic dance music, along with pop. Another playlist, called “I Swore I’d Never Quit”, is more pop music and uses another name, Austin Winters. A third playlist, “Devil in Disguise”, has his raps.
