It was a year before Beckett was charged with first-degree murder.
However, proceedings were delayed when he was further charged in 2012 with offences relating to allegedly trying, while on remand in prison, to arrange the murder of five people associated with the case.
His alleged intended targets included Letts-Beckett's parents, an Royal Canadian Mounted Police Sergeant and an Alberta lawyer.
British Columbia Supreme Court Justice Ian Meiklem has set aside six months for the jury trial, Canadian news website The Province reported.
Beckett is charged with first-degree murder, counselling to commit murder and obstruction of justice.
He is being held in custody at the Kamloops Regional Correctional Centre, inland northeast of Vancouver.
Beckett has been filing applications from behind bars, alleging abuse of process, bias by police and court officials and failure of the Crown to disclose documents.
