Two plead guilty to killing woman outside her home on central Alberta reserve

WETASKIWIN, Alta. - Two of three men charged in the 2011 slaying of a woman on a central Alberta reserve have pleaded guilty to lesser charges.

Chelsea Yellowbird, who was 23, was slain two months after her five-year-old nephew, Ethan Yellowbird, was killed by a gunshot as he slept in a bed in the house next to his aunt's on the Samson Cree reserve in Maskwacis, formerly known as Hobbema.

On Tuesday, Wacey Applegarth pleaded to second-degree murder while Randall Omeasoo pleaded guilty to manslaughter.

Both men had originally been charged with first-degree murder.

A third man, Shelby Minde, is scheduled to appear in court Nov. 13.

The case was cold for two years before a number of tips helped Maskawacis RCMP break the case open.

The reserve, about 90 kilometres south of Edmonton, has struggled with drug- and gang-related violence over the years.

Three teens pleaded guilty in 2012 to manslaughter in Ethan's death. They admitted to taking turns firing a gun at the home and accidentally killing the boy.

Madam Justice J.H. Goss will wait for a Gladue Report to be completed before sentencing. The report focuses on an aboriginal offender’s history and upbringing and will be presented to the court before sentencing occurs.
