Winnipeg police say they’ve made a fourth arrest in the ongoing investigation into a 2023 murder.

Shelly Dawn Hayward, 30, went missing in November of that year, after being last spotted in the Polo Park area.

In early 2024, homicide investigators took over, and four suspects were identified — one of whom had died before charges were laid.

Two women, 24 and 25, as well as a 39-year-old man, had been arrested and charged with first-degree murder by the end of October 2024.

Police said they made an additional arrest Tuesday at the Winnipeg Remand Centre and charged Katrina Musawagon, 32, with first-degree murder as well. Musawagon remains in custody.
