DAYTON, Ohio (WDTN) – A Dayton man will spend at least 36 years in prison for the murder and rape of a young mother.

Karl Coleman, 26, was sentenced in Montgomery County court Tuesday for killing his estranged girlfriend, DeMisha Mattison, in front of her 2-year-old son. The violent crime happened in Mattison’s Clover Avenue home in 2011.

Prosecutors say a friend found Mattison’s body on May 6, 2011.  The child was found wandering next to her body.

Mattison’s family was emotional as the sentence was handed down. Some family members spoke in court.

“She’s missed his first day of school. Going to miss his graduation. She’s going to miss his wedding. She’s going to miss everything. She loved him so much,” said Rosie Moore, victim’s mother.

The family says they are satisfied with the sentence, but nothing can bring their loved one back.

Moore says the boy is doing well. “He’s a little buff ball, full of energy always going, he’s a lovable child.”

Mattison was only 27-years old when she was murdered. provides commenting to allow for constructive discussion on the stories we cover.
