The fourth and final defendant in the robbery and killing of a man who advertised a ring on Craigslist has been convicted in Tacoma, Wash.

The Pierce County prosecutor's office says 24-year-old Clabon Berniard will face the equivalent of life in prison when he is sentenced Sept. 9 in Superior Court.

The jury found Berniard guilty Monday of robbery, burglary, assault and murder charges in the April 2010 home invasion shooting of 43-year-old James Sanders of Edgewood.

Three others who went to the home pretending to be interested buyers were convicted and sentenced to lengthy terms in prison.

Berniard's lawyer argued he wasn't in the home at the time.
