No charges will be laid against the police officer who shot and killed Don Dunphy in 2015, RCMP said Tuesday.

However, Dunphy's daughter says the Alberta Serious Incident Response Team told her there were errors in the investigation, "which resulted in a loss of evidence."

The police force released limited results of its investigation Tuesday morning into the Dunphy shooting, but told reporters that there were no grounds to charge RNC Const. Joe Smyth in the incident.
