Jakob Mumper, a member of the swim teams at the Indiana Swim Club in Bloomington, Indiana and Bloomington North High School, was killed on Sunday in what police believe was a homicide-suicide.

According to local authorities, 61-year old Jeff Mumper shot and killed his 54-year old wife Greta, his 26-year old daughter Emma, and his 18-year old son Jakob on Sunday at their home in Bloomington. He then shot himself as well.

On Monday, memorials for the family have poured out both in the form of a physical memorial on the front porch of the family’s home, as well as online remembrances.

“It’s hard to comprehend what has happened to my friend ,my comrade, my teammate , my fellow brother,” one of his teammates said in an Instagram post this week. “Jakob It was an honor to be your captain and it was an honor to swim with you. I hope your some where safe and peaceful. Your undoubtedly one of the kindest, unselfish, caring person I have ever met. I miss you brother and remember, Just Keep Swimming!!<3”

Mumper was a senior at Bloomington North High School.

Last season, as a junior, Mumper was an Indiana High School Sectionals Champion in the 100 free, defending his title from his sophomore season. He finished 18th in both the 50 and 100 yard freestyles at the State Championship meet.

Mumper was likely to break several school records at Bloomington North High School during his senior season.

“Those were my records from when I went through,” said Bloomington High School North boys swimming coach Max Irwin. “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.”

His older sister Emma also swam at Bloomington North High School and was a State Championship qualifier. She was a graduate student in Clinical Psychology at Stony Brook University after attending undergrad at Indiana, where she did not swim.

Police have not released information about a motive for the shooting. Friends of the family told a local NBC affiliate that Jeff Mumper had beaten prostate cancer, but was then diagnosed with pancreatic cancer.

This has to be one of the most horrifying stories I’ve read in a long time.

To kill your own family…your wife…and your two children? No words. My thoughts and strength go out to the rest of their families and everyone who knew them.
