The trial of a woman accused of being an accessory after the fact to a triple homicide last year west of London got underway in court Friday.

Kirsten Bomberry is charged with three counts of accessory after the fact following the deaths of three Six Nations residents whose bodies were found near Oneida of the Thames First Nation.

Bomberry has pleaded not guilty.

Melissa Miller, 37, her cousin Alan Porter, 33, and his friend Michael Jamieson, 32, were found dead in a stolen pickup truck on Nov. 4, 2018.

Miller was seven months pregnant. Court heard she was stabbed multiple times in the chest. Porter was also stabbed and Jamieson was shot in the chest, the Crown says.

The Crown claims Bomberry buried the weapons that were used in the killings.

Crown attorney Joe Perfetto laid out details to the court of the day the bodies were found. "Hunters observed what appeared to be three bodies wrapped in blankets, bound with cord and covered by a tent in the bed of a pick-up truck," he said. 

He told the court that "the murders occurred at Bomberry's residence the evening of October 28."

The Crown alleges Bomberry hid knives and a shotgun it says were used in the killings.

"Kirsten Bomberry showed (a witness) where she had reburied the weapons in a field off highway 54," Perfetto said.

He went on to say that days after the deaths, there was a constant fire burning at the property.

Nicholas Shipman, 36, Thomas Bomberry, 30, and Jamie Beaver, 32, all of Six Nations of the Grand River are charged in the deaths.

Shipman is facing with three counts of second-degree murder, while Thomas Bomberry is facing two counts of second-degree murder in the deaths of Miller and Porter.

The trial continues Tuesday.
