Like his sister, he was also involved in raising awareness about mental health and served as the president of the Bring Change to Mind group, which helped give students a platform to discuss mental health issues.

His swimming coach Max Irwin told WTHR that Mumper was expected to break swimming records at Bloomington High School North this year.

“Those were my records from when I went through,” Irwin said. “So, to have coached someone who’s now better than me, that’s kind of what you really want as a coach. So, it’s a tough loss on so many levels, the athletics being one of the lesser levels for sure.”
