'Why did my mom and brother have to die?' 2 years, no answers in police-involved shooting

Two years after a 73-year-old woman and her 39-year-old son were killed during a policestandoff in northwestern B.C, there are still no answers as to why they were shot outside their home in a small village of around 300 people.

"Why did my mom and brother have to die?" asked Shonte Williams, referring to thethe incident that took the lives of Shirley and Jovan Williams in Granisle, B.C., about 150 kilometres east of Smithers.

Shone Williams saidshe's received few updates from officials since the deaths.

"Every time I've chatted with[investigators] I'm told, 'Oh, it's just a little bit longer,'" said Williams.

With few official details, Williams has tried to piece the story together herself. She said she's spoken to witnesses and has been upset by some of the details.

"Knowing that they were killed, and I know exactly where... it was horrible," she said.

'Dispute involving a handgun'

Williams' mother and brother were killed April 21, 2016. According toRCMP,police were called to a "neighbour dispute involving a handgun," at around 12:30 p.m. PT.

When they arrived, officers surrounded the home and tried to make contact with the residents.

RCMP said JovanWilliams left the house,confronted the officers and was shot. Shortly after, Shirley Williams also left the house. She too interacted with police and was shot, police said.

The province's police watchdog, theIndependent Investigations Office, was called in to review the case. The investigations office seized both police and non-police weapons, but has not confirmed the type or how they were used.

The Independent Investigations Office's chief civilian officer, Ron MacDonald, said the probe is nearly complete, but added it should have been wrapped up by now.

MacDonaldblamed the delay on a case backlog. He said improving investigation times is a top priority.

"Two years is longer than I find acceptable."

Victims remembered as gentle, generous

At a funeral held in Burns Lake in May 2016, mourners remembered the Williamsas gentle, generous people.

Originally from Memphis, Tenn.,Shirley Williams moved to British Columbia after marrying a member of theCheslattaCarrier First Nation.

Her son, Jovanwas a former U.S. Marine, and a formercustodian, who had recentlymoved toGranisleto be with his mother.

Shonte Williams moved into her mother's Granisle home for a period of time after the shootings to care for family pets, but now lives in the U.S.

She said after the shooting,false rumours spread in the community that family membershad unaddressed mental health issues.

Those rumours, some of which were published in local media, were upsetting, she said.

Granisle 'resilient': mayor

Shortly after the shootings, GranisleMayor Linda McGuire describedthe event as "unsettling," noting the villageis predominantly made up of seniors.

A community meeting was held with the Independent Investigations Office, with a follow-up meeting promised once the report is complete.

McGuire said the level of concern in the community has sincereceded.

"In the last three of four months I've had maybe two inquiries from citizens," she said. "It hasn't, certainly, been prevalent."
