The Worst Gold Diggers Author – please meet Severin Koerner. Not so smart Severin Koerner decided to team up with his not so smart friend Elisa Griffin-Boily and make up a lie that their friend Sarah Barbeau died in a tragic car accident. After a thorough investigation that took over a month we found out that Severin Kaoerner’s female “friend” Winnipeg’s Sarah Barbeau is alive and well.
