CALGARY -- Sunday marked a grim anniversary for family and friends of a slain social worker.

Deborah Onwu, 47, was stabbed to death in a home in the community of South Calgary one year ago.

At the time it was an assisted living property owned by Wood's Homes. She was working along with an at-risk youth.

On Sunday, her loved ones gathered to remember her.

Since the incident, Onwu's supporters have been calling on the government for better safety standards for those on the job.

Correction:

The original version of this story incorrectly indicated the fatal attack took place in the community of Bankview.
