Blood found on the walls, floors, furniture and ceiling of a Crestview home only adds more pieces to the puzzle of what happened on Aug. 8, 2009, when a 16-year-old girl fatally stabbed her mother's boyfriend.

Sgt. Dean Hamm, a blood splatter expert with the Whitehorse RCMP, analyzed hundreds of blood splatters found in the home, but in the end, could not say what sequence of events led to the man's death.

The home's layout is typical of most double-wide mobile homes; a rectangular building with a living room, small dining room and galley kitchen at the front of the house.

From there, a hallway leads down the centre of the home. Three bedrooms and a bathroom open off the passageway, at the end of which is a furnace and the back door.

The dead man's blood was found throughout the home, starting with an "impact” splatter at the far end of the hallway.

The relatively large blood droplets which splashed against the side of the furnace were the result of a medium-force impact, Hamm told youth court during this week's trial – "a punch or possibly a stab.”

He noted too, that the impact pattern is only created when a pre-existing wound is struck, so the victim would have already had at least two open wounds at that point.

Dozens more smears and splatters coloured the walls of the hallway leading to the front of the house, some as high as the ceiling.

Hamm could not say if these spatters were left by the victim, or by someone else covered in his blood moving down the hall.

In the kitchen, the stove, counter and refrigerator are spattered with more blood, as if the victim were stabbed once again, or more likely, said Hamm, blood from his lungs sprayed from his mouth or open wounds as he supported himself on the corner of the fridge.

From the kitchen to the dining room, pools of blood show the man spent a "fair length of time” there, Hamm said.

Photos from the living room show a gory mess on the floor where the man ultimately expired.

It was there that the man's girlfriend and her son found him and attempted to staunch the flow of blood with towels as they waited for an ambulance to arrive.

Finally, a pair of bloody sock prints were found leading down the front stairs to the street.

Summing up his findings, Hamm said he could not determine if the girl pursued the man through the house, nor the timing and sequence of events.

The girl, now 17 years old, has pleaded guilty to manslaughter, but is on trial for second-degree murder.

She is being tried in youth court, so her identity cannot be published.

The names of her victim and family members are also protected, as publication would identify the accused.
