Memorials to honour four Mayerthorpe Mounties killed in line of duty 20 years ago

MAYERTHORPE, Alta. — Memorials are being held Monday for four Mounties killed 20 years ago in the line of duty at Mayerthorpe, Alta.

Peter Schiemann, Leo Johnston, Anthony Gordon and Brock Myrol were called in 2005 to search a farm near the town, following reports of a marijuana grow-op and stolen vehicle chop shop.

They were ambushed and gunned down by James Roszko, who then shot and killed himself, in one of the largest multiple officer killings in Canadian history.

Military fighter jets are to fly over the Fallen Four Memorial Park in Mayerthorpe to mark the anniversary.

A service is also to be held at the park.

RCMP say the day was one of the most tragic in its history and that the legacy of the four live on in every officer who serves.
