The defense was first to present its closing arguments.
Attorney Joe Cawley argued, quote, "A lack of evidence, is not evidence. A lack of evidence, is reasonable doubt."
Michele Harris has been missing since September 11, 2001.
Cawley argued there's no body, no other physical evidence and no weapon to prove Cal Harris killed her.
Cawley told the jury Cal provided for his family while Michele was spending time with her boyfriends.
The defense says Cal cooperated with the police investigation, but argued police were so focused on Cal that they neglected other possible suspects.
Cawley says there were not enough blood stains in the Harris home to link them to murder.
During the prosecution's closing arguments, District Attorney Gerald Keene said those blood stains are the critical evidence in the trial.
Replaying the videotaped testimony from forsenics expert, Dr. Lee, Keene told the jury the blood proves Cal murdered Michele.
Keene called Cal a manipulative, controlling husband who planned his wife's murder for months.
Keene reminded jurors of testimony that Cal said he could kill Michele without a gun and no one would find her body.
The prosecution says that proves the husband's intent to murder his wife.
Keene told the jury, quote "In the garage is where Michele shed the last drops of blood."
Jurors have asked to hear the testimony of Michele's boyfriend, Brian Early again.
He was the last known person to see her alive.
They're also reviewing the testimony of Early's landlord, who said he was fidgety while talking about Michele's disappearance.
During 10 days of testimony and arguments, the jury heard from 48 witness and viewed more than 250 exhibits.
Again, jury deliberations have stopped for the night at the request of the jury.
They're scheduled to resume at 8 o'clock Thursday morning.
