In July 2008, Nancy Cooper's body was found in an unfinished Cary subdivision days after being reported missing.
Earlier in the morning, the defense questioned whether police reports and timelines written months after Nancy's husband's arrest were accurate since he was charged three months after Nancy Cooper's murder.
The lead detective on the case said they are accurate and that Cooper cleaned inside his house in the days after the murder to cover up the crime.
"She goes away, he gives her $700 to go on vacation, she comes back, arguing with him what he had not done and he was upset about it," Cary Police Det. George Daniels said. "This goes on the whole week. This goes on continually. On Friday it goes on from 9 a.m. until whenever he states. I believe that had something to do with the cleaning, had something to do with the next level to the next step to the next step, which lead to her death, which I believe Mr Cooper did."
On Friday, Daniels pointed out to jurors specific inconsistencies Brad Cooper made to police.
In July 2008, Brad Cooper answered investigators questions in person when his wife was missing. But after her body was found not far from their Cary home in an unfinished subdivision, he was asked to answer the questions a second time.
He again answered many of the same questions during a taped child custody deposition in October of 2008 - this time from Nancy Cooper's divorce attorney.
"Have you ever seen any other e-mails that I sent to Nancy?" asked attorney Alice Stubbs in a October 2008 deposition.
"To the best of knowledge, no," replied Brad Cooper in the October 2008 deposition.
Detective Daniels, after that video clip played in the courtroom, said Cooper had lied - that he had read e-mails to his wife from her attorney.
"He tapped into her e-mails to view it we later found out," Daniels said. "And that's why it stuck out to me when he said he hadn't viewed them where, in fact, he had viewed them prior to Nancy viewing them."
