Alcohol abuse, jealousy and an unwelcome sexual advance. Crown Prosecutor Rob Parker laid the foundation of his case Thursday at the manslaughter trial of Tony Warken.

Warken is accused of killing his best friend, 65 year old Gordon Gregson in November 2009.  Gregson's body was found near a hot tub in a Bengough home.  A pathologist says he died from compression of the neck causing extreme trauma with deep muscle bruising.

In his closing arguments to the jury, Parker suggested that alcohol, jealousy over a recent paycheck and an unwanted sexual advance by the victim, led to a physical altercation that ended with Gordon Gregson's death.

Warken took to the stand in his own defence Thursday and testified that he backhanded his friend in the head after Gregson made a sexual advance towards him, but doesn't remember doing anything else.  Parker suggested, Warken may have blacked out after a day of heavy drinking.

"Mr. Warken indicated that after he backhanded the deceased he left the area, came back 20-30 minutes later to find the deceased floating in the hot tub. The Crown's position is that is not what happened and that there was further violent acts towards Mr. Gregson."

"Through out the course of the evidence there were two interviews presented." explained Parker. "the common theme through out the interviews was that Mr. Warken had indicated, in response to questions from the investigators, that he just did not remember."

Several times during the interview with police, Warken changed his story about when he had last seen his friend alive and when the officer confronted him on his ever changing story, Warken responded by asking the officer if he always remembers everything that happens when he's been drinking.

Merv Shaw is defending Warken in the trial and explained to the jury in his closing arguments that the trial is a simple one.  Do they believe what the police and Crown are suggesting or do they believe what his client is saying?

"We have two people, the deceased and my client. My client was the only person there. There is no great technical evidence, there are no other potential suspects and it really is a straight forward and simple case."

Shaw told the jury that there has been a great burden placed upon their shoulders, saying they have the tough but very necessary task of sorting through the evidence and deciding what they believe and what they don't, including what caused the injuries to Gregson's neck.

"I'm suggesting that the trauma to the neck was caused by my client trying to pull the victim from the hot tub... basically trying to pull the dead weight from the hot tub and that's what caused the trauma to the neck."

With all of the evidence and testimony presented, it's now up to the jury to decide what they think happened. The judge gave his final instructions to the jurors earlier Friday and now they will be left to discuss a verdict.

At last word the jury is still deliberating. If no decision is reached by late Friday night, the jurors could be sequestered over the weekend.
