A man battling cancer killed his wife and two kids in an apparent murder-suicide in Indiana, police said Tuesday. The incident took place early Sunday in Bloomington, news station WXIN reported.

Jeffrey Mumper, 61, allegedly fatally shot his wife, Annamarie, 54, daughter Emma, 26, and son Jakob, 18, before turning the gun on himself. 

The Bloomington Police Department responded to a home in S. Olcott Blvd. for a welfare check on the occupants. Police were notified after a woman went to the house to pick up a friend. When no one answered the door, she entered with a key and found her friend unconscious. 

Friends said Jeffrey had survived a bout of prostate cancer, but was now fighting pancreatic cancer, news station WTHR reported.

Jakob's friends arrived at his home to pay their respects, the outlet reported. 

“I felt they were like my second parents, to be honest,” said one friend, who identified himself as Joe T. “I loved his dad. I loved his mom.”

Jakob was an elite swimmer at Bloomington North High School. He was likely to break several school records this 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." 

Emma was a graduate student at Stony Brook University in New York.

A motive remains unknown, and authorities said an investigation is underway.
