The prosecution again focused on evidence was collected from the Harris home in Spencer, including blood samples.
But the defense questioned why State Police did not pay the same attention to other men in Michele's life, and their homes.
New York state police investigator Steven Anderson returned to the witness stand.
He's been testifying about red stains found in the kitchen and garage of the Harris Home.
Defense Attorney Joe Cawley pressed Anderson to point out the pictures of the stains were blown up for the jury, and don't represent the actual size.
Anderson testified he also looked Cal Harris over closely for bruises or cuts to see if there were any signs he had been involved in a struggle.
The defense then asked if Anderson paid the same attention to 3 men Michele knew well or had affairs with.
Anderson said no.
Once the van and blood specks were found in the Harris home, it become their sole focus.
Also, there has still been no testimony about where blood was found that matched the DNA of Michele Harris.
The prosecution also put witnesses on the stand who testified about the plans Michele was making for the couple's divorce.
She put a down payment on a house in Owego.
She planned to sell her engagement ring.
A friend, Lisa Feuer, said Michele was going to visit her in New York City September 13th.
They spoke the morning of September 11th, and Feuer never heard from Michele again.
State Police say harris disappeared later that night.
