NOTE: This story has been updated since it was first posted online to include more sentencing information.

Two Maskwacis men charged with the second degree murder of a 20-year-old in Montana Cree Nation and assaulting a bystander three summers ago have been sentenced. 

Cole Gerald Cattleman 27, and Chaz Joseph Cattleman, 25, were each charged with second degree murder and aggravated assault. Chaz was also unlawfully at large from parole. 

A trial was scheduled for April 7 to 17, 2025, at the Wetaskiwin Court of King's Bench. The Hon. Justice Larry R.A. Ackerl gave his decisions and sentences on April 16, 2025. 

Cole was found guilty of second degree murder and sentenced to life imprisonment with no parole eligibility for 10 years. He also received a firearms prohibition, a DNA order and an item seizure order.

Chaz was found guilty of manslaughter and given nine years and 11 months minus time served in pre-trial custody at an enhanced credit of 1.5 days totalling 1,412 days credit, leaving about six years left to serve.

Justice Ackerl recommended Chaz be allowed to serve his sentence at the Pe Sakastew Centre in Maskwacis, however the decision is at the complete discretion of Corrections Services Canada.

On July 24, 2022, two males entered a residence and attacked Mason Skylar Currie, 20, with a weapon, according to RCMP. Currie died of his injuries.

The suspects came across a bystander who was calling 911 and allegedly assaulted him as well. 

Awaiting sentencing

Two Wetaskiwin men convicted of manslaughter are awaiting sentencing. 

Morgan Maslin, 22, and Adam James Cook, 30, were found guilty on March 24, 2025 at the Wetaskiwin Court of King's Bench.

Antwon Bull of Ponoka, 19, was chased down and stabbed 11 times with two weapons - a knife and a broken beer bottle - on July 8, 2022, close to the 7-Eleven gas station in Wetaskiwin.

The trial judge determined the Crown had proven Bull's death was a culpable homicide, however, although she found the two accused had planned to confront Bull, she wasn't satisfied the Crown had proven either of the men had intended to cause bodily harm that was likely to cause death. 

The next court date was scheduled for April 8 to set a date, but the matter has now been set over to June 10.
