The lawyer for a man accused of killing two great-grandparents, burning their motor home and hiding their bodies says the case against his client is just speculation.

Brian Beresh told a court in Edmonton that the Crown has failed to prove the most basic elements of its case against Travis Vader, formerly of Summerland.

In his closing arguments, Beresh says there's no evidence the St. Albert couple was even murdered.

Beresh says the Crown's chain of circumstantial evidence is good enough for vigilantes, but not the courts.

Lyle and Marie McCann disappeared on July 3, 2010.

Their bodies have never been found.
