The Chief Coroner of the Northwest Territories has confirmed that a young woman living in Yellowknife died from a mixture of alcohol, cocaine and morphine.

On May 13, 20-year-old Jessica Koe-Jerome was at a cabin with a friend about 20-kilometers outside the city.

They had been drinking that night.

Koe-Jerome was later found unresponsive.

Toxicology tests showed she had a lethal cocktail of cocaine, morphine and alcohol in her system.

Coroner Cathy Menard said deaths such as this are all too common.

"Forty-nine per cent of suicide deaths have alcohol or drugs in their system. Fifty-seven per cent of accidental deaths have alcohol or drugs in their system. Seventy-six per cent of our homicides have alcohol or drugs that are contributing factors into the death."

Menard said drugs and alcohol are the leading contributing factors to deaths in the N.W.T. She said statistics like these are proof more work is needed to raise awareness of the dangers of alcohol and drug use.
