Four people were killed, including two policemen, during a shooting this morning on a quiet suburban road in Canada. MacCoubrey added that it sounded as if the gunfire was coming from the middle of the square in his apartment complex. "In this time of shock and grief, let us all protect their families", O'Brien said in a tweet Friday morning.
He said police have been searching the buildings, and he's been sitting away from windows.
"It was scary", said Marlene Weaver, who was in bed on Friday morning when she heard shots ring out in her neighbourhood.
Earlier, police confirmed the shooting "resulted in at least four people killed". "They have to rise above it, carry on with their job and be objective but at the same time, police officers are human beings and it's a very hard situation", he said.
