In his opening statement Crown counsel John Swanson told the jury that Robotti and Roxanne Louie, 26, had a strained relationship due to differing opinions on the nutritional and developmental needs of Louie香蕉视频直播檚 three-year-old son.

These differences reached a tragic peak Jan. 4, 2014 when Louie was killed during a fight while staying over at Robotti香蕉视频直播檚 Penticton home. Her body was found in Naramata nearly a week later.

The two women香蕉视频直播檚 lives became intertwined in 2011, when Louie dated Robotti香蕉视频直播檚 grandson Dylan Spence. They had a child, but were only together until October of 2012 when a violent fight set them apart.

An acrimonious custody battle between the two followed and when Spence was granted visitation it was held at Robotti香蕉视频直播檚 home because he worked in the Alberta tar sands.

The child even had his own bedroom at his great-grandmother香蕉视频直播檚 and was visiting her in Penticton when trouble erupted.

Louie had moved to Vancouver from the South Okanagan earlier in 2014 and Robotti had traveled there a couple of weeks before Christmas to pick up the boy.

Swanson told the court Louie hadn香蕉视频直播檛 firmed up plans herself to return to the South Okanagan for the holidays at that point.

Around Dec. 27, 2014, Louie decided she wanted to visit with family and made the trip to the Okanagan.

At some point while there, Louie went to Robotti香蕉视频直播檚 to pick up the boy for a day of family tobogganing. Swanson told the court the he didn香蕉视频直播檛 want to leave his great-grandmother香蕉视频直播檚, so Louie stayed overnight instead. The next day Robotti bought the boy a snowsuit and drove them both to Louie香蕉视频直播檚 for the snow day.

The boy eventually returned to Robotti香蕉视频直播檚 and Louie went to stay with her father. After an argument with him, she opted to stay with Robotti.

The child witnessed the conflict and was in the room crying. At some point Robotti香蕉视频直播檚 brother Pier went to the home and helped calm the child.

As Pier put the child to sleep the argument raged on.

It started in one room, escalated to a physical fight and moved into another room with the women 香蕉视频直播渉itting each other and pulling each other香蕉视频直播檚 hair,香蕉视频直播� Swanson told the jury.

The effort to subdue Louie continued, but she didn香蕉视频直播檛 stop fighting.

Autopsy evidence indicates that Louie took at least 26 blows to the head and it could have taken from 15 minutes to three hours for her to die from the injuries incurred.

After she died, Swanson said Grace Robotti asked her brother to take the body from the home and started a 香蕉视频直播渇everish effort香蕉视频直播� to clean up so the child wouldn香蕉视频直播檛 wake to see the carnage.

While she took Louie香蕉视频直播檚 belongings and the crowbar to dumpsters around the area, Pier dumped Louie香蕉视频直播檚 body down an embankment in Naramata where it was covered in a heavy snowfall.

Robotti then planted a story that Louie left of her own volition and she doesn香蕉视频直播檛 know where she is. A missing person香蕉视频直播檚 investigation got underway.

Crown counsel will call 17 witnesses over the trial that香蕉视频直播檚 scheduled to carry on until April 14.
