OTTAWA (WEEK) -- After a week of witness testimony, a jury will begin deliberating the fate of Ken Cusick on Friday.
The 52 year old is being charged with murder in the death of his wife, Tracy Cusick.
Jury deliberations are to begin Friday after closing arguments.
On Thursday, the defense rested its case after a second forensic pathologist testified that Tracy Cusick died of a drug overdose, and was not murdered as the prosecution claims.
The primary disagreement throughout the trial has been the cause of death.
Prosecutors say Ken Cusick drowned his wife in a toilet bowl, the defense says she overdosed. Soon, it will be up to the jury to decide.
Over the past seven days, we've heard from family and friends of the Cusicks, in matters such as the couple's strained marriage.
A handful of experts have taken the stand, giving contradicting opinions on whether Tracy Cusick died because of drugs in her system, or at her husband's hands.
Dr. Shaku Teas said in his testimony Wednesday that Tracy Cusick being murdered is impossible to be certain of due to the findings of a potential drowning can be the same as an overdose, or other sudden deaths.
On Thursday, the jury saw photos of Tracy Cusick's body, taken after she was exhumed for the second autopsy.
Ken Cusick looked away as the photos scrolled through, shortly before he decided not to testify in his own defense.
If convicted, Ken Cusick faces 20 to 60 years in prison.
