Inquiry delayed into Winnipeg woman's death in B.C.

A Winnipeg family is frustrated after learning an inquest into their daughter's death has been postponed.

Sheilah Sweatman was working as a search-and-rescue volunteer in Nelson B.C. last year.

The 29-year-old volunteer was helping with a recovery mission on the Goat River when she became tangled in cables and dragged underwater.

She was the first search-and-rescue volunteer in B.C. to be killed in the line of duty in 15 years.

Sweatman was living in a small community near Nelson at the time. She had about two years experience in search and rescue service, and was assigned to the Kootenay Swift Water Specialists Team.

Her father, Wynn, has been preparing for an inquest for months, hoping to find out what went wrong and how it could have been avoided.

But on May 29 he found out it had been postponed just days before it was to begin.

'To not get their act together over 11 months, it's disgraceful and very, very sad," he said.

“Nobody should wait this long. And now there are volunteers still at risk because there are things to learn."

The sooner an inquest into their daughter's death is complete, the better chance there is to stop an accident from happening again, Wynn said.

According to officials in B.C., the inquest will now start Nov. 19 in Nelson.
