Leonard Osmond said police have told him and his wife they won't know how their daughter died for six weeks to six months.

Osmond, 29, was Leonard and Sharon Osmond's only child. She died last weekend in what police are calling suspicious circumstances.

Osmond, a community health nurse working in Behchoko, was celebrating Halloween with friends in Yellowknife on Saturday evening.

Police were called to a Ravenscourt apartment on Nov. 1 around 11:30 a.m. They found Osmond unresponsive. She was pronounced dead at the Stanton Territorial Hospital shortly thereafter.

Speaking from his home in Hermitage-Sandyville, N.L., Osmond said he'd heard an intravenous device and drugs being involved in his daughter's death, which upset him greatly.

"Tara wasn't one for that stuff. I can tell you that now. That's why I was so surprised when I heard a couple of things. That really made us upset and mad. She should've known better," he said.

He said he'd been speaking to the RCMP, who told him the investigation is ongoing.

"I don't exactly know what happened. One (nurse) was questioned, I believe," he said. "They're not going to tell us nothing. They won't tell me nothing until they know for sure."

Sgt. Wayne Norris said the police are waiting on information from the medical examiner's office and the lab before they release any further information.

"We can't go on maybes. We need to get the results back to determine what the exact cause of death was. The investigation is ongoing," he said.

He confirmed people have been questioned in relation to Osmond's death.

"People were spoken to because it was suspicious in nature. It's not appropriate, for us to say, 'maybe this, maybe that,'" he said.

Norris wouldn't comment on whether an intravenous device was involved.

"We don't operate on rumours. We operate on facts," he said.

Officials from Stanton Territorial Hospital declined to comment and said it was an RCMP investigation.

When asked if intravenous drug use among health care workers was a concern, hospital CEO Kay Lewis said she hadn't heard of it being an issue.

"It's certainly not something I'm aware of. It's pretty hard to start an IV on yourself," she said.

Ryan Hewlett, the nurse in charge at the Behchoko Health Centre where Osmond worked, said he was in Yellowknife with her on the night she died. He said news of her death came as a shock on Sunday morning.

"The last time I saw her we were downtown. A group of us went downtown. Everyone was having a good Halloween," he said. "I left with my wife and we thought everything was fine."

Hewlett, who hired Osmond and lived in the same Behchoko apartment complex as her, confirmed he had also heard an intravenous device may have been involved in Osmond's death, but said the rumour was a shock.

"I never did see anything. If there was any indication of anything, I never did see anything," he said. "She wasn't that type of person. She was professional in her job, she showed true professionalism in her practice. To me, that was definitely a surprise."
