LOUISVILLE, KY (WAVE) - Two young children were found by a family member inside their Venango Drive home on Friday.
The children were alive, but their parents, Catherine and Mike Miles, were not.
"It breaks my heart because I live right next door and they were in there by themselves," a neighbor said.
Police stepped into a gruesome scene inside. The couple had been shot to death.

"They were very nice," the neighbor said. "They always waved, but knowing that there were all these adults around here, and there were children by themselves and none of us knew to help them -- It makes, it makes me very sad."
Mike's sister Geneva was also found dead in the home.
Police pulled over their killer, Christopher Olivo, 47, in Hernando County, Florida just before 10:15 p.m. on Friday.
Olivo had his nearly three-year-old daughter with him.
Geneva was the child's mother.
Police said Olivo took her with him after killing her mother, aunt and uncle.
Family are still trying to wrap their minds around everything. They hope the children won't remember the tragedy.
"They had to be there when it happened you know," Keith Harris, a family member said. "I know they may be young, but you know it still hits hard."
The Louisville Metro Police Department is currently working with authorities in Florida. They're planning to have a press conference regarding Olivo's capture on Monday.
