A man who told police he was 鈥渏oking around鈥� with his girlfriend when he fatally shot her in the head has been sentenced to four years in prison for manslaughter with an additional six months for possessing a rifle without a licence.

The British Columbia provincial court decision in Vancouver says Trevor Brown was 18 when he shot Anichka Loeffler, who was also 18, in November 2020.

The decision issued this week says Loeffler was struck in the head by a bullet discharged from an unlicenced semi-automatic .22-calibre rifle in the bedroom of the home where Brown was living with his mother and grandmother.

The decision says Brown initially told police that Loeffler had shot herself accidentally while the pair were smoking marijuana and playing around with the gun, but he later admitted he 鈥渙nly pointed the gun at her head for a split second.鈥�

It says Brown鈥檚 mother told police she heard the sound of a shot and when she went to check what had happened, Brown said he 鈥渢hought the safety was on.鈥�

The sentencing follows Brown鈥檚 guilty pleas in May to charges of manslaughter, unlawfully possessing and pointing the gun at his girlfriend and using it carelessly.

The decision by Judge Gregory Rideout outlines some mitigating factors, including Brown鈥檚 young age, lack of criminal record and family support.

But the judge found Brown鈥檚 actions were aggravating, including failing to determine whether the rifle鈥檚 safety was on, or if the gun was loaded before he pointed it at his girlfriend鈥檚 head and pulled the trigger.

鈥淚 do not find he exercised a momentary inadvertence or lapse of judgment. Rather, I find there were a chain of inherently dangerous actions and careless conduct that resulted in (Loeffler鈥檚) death,鈥� Rideout says in the decision.

Rideout also notes Brown 鈥渋nitially placed the blame鈥� on Loeffler.

A pathologist later determined there was no evidence of close-range firing as there was no indication of gunshot or powder burns on her body, the decision says.

The judge also sentenced Brown to six months to be served concurrently for the remaining two offences related to his use of the rifle.

The decision says Brown admitted the .22-calibre rifle belonged to a friend who he refused to name, and he鈥檇 had it in his possession for about six months.

Brown has been handed a lifetime weapons prohibition and he鈥檚 barred from contacting several members of Loeffler鈥檚 family.
