The man shot and killed by the RCMP on a farm east of Edmonton had been in trouble with police before, reveal court documents.

Russell Skoropad, 43, was already facing charges of assaulting his mother when he was shot to death by police on the woman's farm northeast of Vegreville Wednesday.

The charge was filed in April after an incident on the same property.

One year earlier Skoropad was handed a 27-day sentence in jail on charges of resisting a peace officer, uttering threats and unsafe storage of a firearm.

The news of Skoropad's death shocked neighbours, who said Skoropad's history with the law was no secret.

"It was a troubled family," said Darlene Ballash, who lives nearby with her husband Ray. "There were issues and there were struggles I'm sure."

They are now waiting to find out what exactly happened Wednesday.

"Usually it never comes to this," said Ray Ballash. "This is the last thing you want to see so it's very surprising that way,"

Skoropad was shot and killed by a single round late Wednesday afternoon, 1½ hours after three officers arrived at the farm on a "trouble with man" complaint.

Police recovered a shotgun from the scene.

The shooting is under investigation by the Alberta Serious Incident Response Team, which investigates serious injury and deaths resulting from the actions of a police officer.
