The town of Parsons is torn apart over the murders of a mother and her three children, but no one is more heartbroken than their father. "They're what I live and breathe for.  I don't know how anybody could do this," said Donald Betts.

Betts spend everyday of their lives being dad to his three kids Hollie, Jaxon, and Averie. He does not know how he will go the rest of his life without them. "Jaxon loved breakdancing and karate, such a silly boy. Hollie playing football. She hung with the best of them. Just letting them know they had somebody in their corner. They had a dad they could always lean on," said Betts.

Betts brought the three children into the world with Cami Umbarger. Police found all four of their bodies at their Parsons home. "They didn't deserve this. Nobody deserves this," said Betts.

He says Umbarger was a wonderful mother who worked hard to make sure her children always had what they needed. He cannot imagine why anyone would do this. "I used to be the baby daddy that was like, no you can't have this guy around my kids, and the one time I chose not to something like this happens. I know I shouldn't beat myself up over it because it's not my fault but I just wish people would please, please watch who's around your kids. Watch who you let in your lives," said Betts.

As investigators search for answers, Betts wants others to remember Umbarger, their daughters Hollie and Averie, and their little boy Jaxon, whose lives were taken too soon. "I love y'all so much and I am so, so, so sorry that I couldn't be there. I know my babies needed their daddy and I wasn't … I just, I love you all. Please just do whatever you can to help me have my babies remembered."

The family plans to hold a funeral service December 2nd.
