Lafond vowed to fight for justice in holding those involved in Bird's death accountable.

"He was taken too young," Lafond wrote.

Birdwas serving two years and seven monthsfor breaking and enteringand related offences.

Riot may have been triggered over food portions

A senior union officer says the deadly riot may have been triggered by a simmering dispute over food portions.

James Bloomfield, regional president with the Union of Canadian Correctional Officers, said there was trouble brewing in the kitchen in the days leading up to the riot.

"However, the inmates, at that point, refused to lock up," said Bloomfield. The number of inmates refusing to lock up ranged from 185 to 200, he said.

Shots were fired by guards as they took control of the area,sending five to hospital. Theinjuries are notconsidered life-threatening.

Canteen concerns

John Hutton, executive director of the John Howard Society of Manitoba, which runs a reintegration program for inmates at provincial and federal facilities, said he isaware of concerns about changes to the way the canteen operates at prisons in his province.

"Apparently there's been some changes in the way the canteen is being administered for all of western Canada, so that would include [Saskatchewan Penitentiary]as well."

• Prison food after cutbacks called disgusting and inadequate by B.C. inmates
• Saskatchewan privatizing food services in jails

He said the food services for the canteen have been privatized and"one of the concerns is that the prices have gone up in the canteen and there may be some issues around availability."

He said inmates sometimes purchasecanteen food to supplement their meals.

Hutton added that food could be a major factor influencing the dynamic inside a jail or prison: "It's very important to have good and adequate food because if you don't, people can get restless. That can certainly cause problems."

Prison ombudsman investigating

Prison watchdog Howard Sapers said in his experience the issue is likely bigger than food.

"There's been a lot of changes around food in Canadian penitentiaries and so it's not just that there wasn't enough food or just that the food wasn't very appetizing, although both of those things may be true there's usually a lot more behind it," Sapers told CBC Radio'sMorning Edition.

Sapers said while double bunking and use of segregation is down in federal prisons, other things have the institutions in flux.

"We've seen trends going up in terms of assaults, use of pepper spray, use-of-force incidents, lockdowns. [Prince Albert] is not unique in that regard," Sapers said.

Staff from Sapers' office are on their way to Prince Albert today to further investigate the cause of the riot.
