Edmonton police say charges have been laid in the deaths of two officers who were shot while responding to a call in March.
Const. Brett Ryan and Const. Travis Jordan were responding to a family dispute at an apartment building when they were gunned down by a 16-year-old boy.
Police said the teen also shot and wounded his mother during a struggle over the gun.
The boy then shot himself and died at the scene.
Police say they will release details about the charges at a news conference later today.
A staff sergeant with the guns and gang section is to be in attendance.
