A fifth man convicted in London, Ont., of the mass slayings of eight men associated with the Bandidos biker gang has declared his intent to appeal.

Brett Gardiner was convicted last month of six counts of first-degree murder and two counts of manslaughter.

He has filed his inmate notice of appeal, on which he writes the verdict was "unreasonable and contrary to the evidence."

Dwight Mushey, Michael Sandham, Marcelo Aravena and Frank Mather have already filed their inmate notices of appeal.

Wayne Kellestine, portrayed at trial as the mastermind of the murders, has not filed one, though the deadline has not yet passed.

The bodies of the eight Toronto-area men were found on April 8, 2006, stuffed into four vehicles on and around a rural property in southwestern Ontario, just kilometres down the road from Kellestine's farmhouse.
