"I've been to a lot of crime scenes, and this one will always stand out in my memory," Woodruff said.
Police said they found the five bodies just after 10 p.m. Saturday.
Police identified the victims as William Burtron, 69; Sheila Burtron, 68; Christie Lee, 33; Bailey Burtron, 16; and Iiaonna Green, 18.
Deputies said they were called to the home for a welfare check because one of the victims hadn't shown up at work for a few days.
Police did not find a gun inside the home but said four of the five victims were shot to death. Police say the bodies were found in different rooms in the home.
After discovering their bodies, police immediately began a search for Lee, who was married to Christie Lee.
Investigators believe the killings happened sometime last week.
Woodruff said Lee did not have a gun on him when he was arrested.
"Why he did it is the big question, and that's what we're wanting to know and that's what the family wants to know is why," Woodruff said.
