EDMONTON - A man once charged in the slaying of two Alberta seniors has been found not guilty of nine unrelated drug and weapons charges.

Travis Vader did plead guilty to a charge of failing to comply with a court order in 2010 and was sentenced to one day of time already served.

His defence lawyer says Vader, who has been in jail since shortly after the couple disappeared, should be released from custody later today.

Vader had faced first-degree murder charges in the deaths of Lyle McCann and his wife, Marie, but the charges were stayed earlier this year.

The couple, both in their 70s, were last seen alive more than four years ago when they fuelled up their motorhome in their hometown of St. Albert, north of Edmonton.

Their bodies have never been found
