KILLAM, Alta. – RCMP in Alberta have laid attempted murder charges in the shootings of two officers earlier this week.

Sawyer Clarke Robison has been on the run since the officers were shot on his property near Killam, about 160 kilometres southeast of Edmonton.

Police had previously named the 27-year-old as a person of interest in the case.

Both officers have undergone surgery at Edmonton hospitals and are expected to recover.

RCMP says they consider Robison a high risk because he may be armed with long-barrelled weapons.
