Peter Khill murder trial: What does the law say about self defence?

The question of whether or not Peter Khill acted in self-defence when he shot and killed Jon Styreswill be at the centre of the jury's considerations as they begin deliberating in his second-degree murder trial.

The seven men and five women who make up the jury were charged by Superior Court Justice Stephen GlitheroTuesday and have retired until they reach their verdict.

• Jurors hear Peter Khill in 911 call saying he feared for his life when he fired fatal shots

Khill, 28, admits he killed Styres by shooting him twice with a 12 gauge shotgun. He's charged with second-degree murder, but is pleading not guilty saying he believed Styreshad a gun so he acted in self-defence.

Styres, from Oshweken, Ont. on the Six Nations of the Grand River was 29 when he was killed. Court heard he was trying to steal Khill's2001 pickup, but wasn't carrying a gun when he was killedaround 3 a.m. on Feb. 4, 2016.

But the judge explained to the jury it's possible Khillstill acted in self-defence as long it was "reasonable" that the Hamilton-area homeowner believed he was in danger.

Glitherosaid jurors will have to consider three questions when it comes to self-defence:

• Did Peter Khill believe on reasonable grounds that Styres was using force or threatening to use force against him?
• DidKhill shoot Styres to defendhimself from a use of force or threat of force from Styresthat he reasonably thought was taking place?
• Was what Khilldidreasonable considering the circumstances as he knew them or understood them to be?

The justice also told jurors they have three options when it comes to their verdict:

• Not guilty
• Guilty of manslaughter, but not second-degree murder
• Guilty of second degree murder

A verdict of second-degree murder can only be reached ifKhillhad the state of mindrequired for murder, explained Glithero. That is, whether the Crown has proved beyond a reasonable doubt that Khilleither meant to kill Styresor to cause him bodily harmhe knew was "so serious and dangerous" it was likely to cause the death.

Manslaughter refers to ahomicide that's committed without the intention to cause death, although there may have been an intention to cause harm.

• Murder vs. manslaughter

Here the judge reminded jurors of testimony from Khill himself who said on the night of the shooting he loaded his gun and went outside his goal wasn't to kill whoever was out there, but to "defend myself." When asked in followup questions whether that meant causing serious bodily harm that could potentially kill someone else, Khill said "Yes."

He also reiterated that it's up to the Crown to prove beyond a reasonable doubt that Khill's actions were "unlawful" and not self-defence the accused is presumed innocent.

Crown says Khill took the law into his own hands

The judge summarized the Crown's position, saying they argue Khillwas not acting in self-defence and that instead of calling the police and staying safe in his home when he realized his truck was being broken into, he "took the law into his own hands."

"Evaluate based on your common sense ... and life experience," Glithero told jurors before sending them off.

The accused, dressed in a dark suit, watched expressionless as the jurors filed out to decide his fate.

Jury asks about a 'reasonable person'

Around 5 p.m. lawyers, family members and media were called back into the courtroom to hear a question raised by the jury.

The 12 people asked whether the definition of a reasonable person in the judge's charge was based on everyday nature or limited to the night of the shooting alone.

Glithero explained the definition the court is looking for is whether a reasonable person with the samecharacter and experienceas Khillwould think firing the shotgun was reasonable within the circumstances.

"Mr. Khillcan think it's reasonable, but the question is whether, in your view, it's a reasonable reactionthrough the eyes of someone with Mr. Khill's qualities ... keeping in mind military training but also that he needs to obey the law."
