Prosecutors said after Doerman came home that Thursday morning from Kroger, stopped to get beer, went to the shed behind his home as his family arrived from running errands. His ex-wife made them all lunch.
"The defendant says to Laura, 'This will be my last good meal,'" Tekulve said, describing what Doerman said hours before the murders. "Laura begins to worry that this is a statement he may be contemplating suicide."
Tekulve also said Doerman called his father around 12:50 p.m.
"Makes a statement that Clayton is going to be the hardest one," Tekulve said.
Between 1-3 p.m., Tekulve said Doerman was doing yard work and playing with his sons. Everything at this point seemed normal. Then between 3:30-3:45 p.m., Doerman is reading the Bible to his son Hunter.
"He's walking around the house with the Bible, mumbling 'Chad knows what's right, Chad knows what's right,'" Tekulve said. "Laura says, 'You're scaring me.' Again, highly unusual behavior and Chad says, 'I'm just playing around.' Our position is he did this to, again, alleviate any fears or concerns that may been in her about her safety, his safety or the safety of the boys, or Alexis so he actively deceived her."

We asked Tekulve if prosecutors knew what Doerman's motivation was for these murders.
"No idea, don't know, why that will probably never be answered, you look at this nice little family, sweet little family, I can't speculate as to why it happened, can't do it," said Tekulve.
On Monday, WCPO found out Doerman is in the process of being booked from the Clermont County Jail, into the Department of Corrections, where he will spend the rest of his life in prison.
Clermont County prosecutors said Doerman gave inconsistent statements to law enforcement, and doctors that differed from what he told his family.
