Details are still sketchy, but at least one person is dead and several others are injured after a gunman in the Eaton Centre, downtown Toronto’s main shopping mall, opened fire on a crowd of people.

Not to diminish the seriousness and sadness of this in any way, but it’s worth noting that Toronto Blue Jays third baseman Brett Lawrie was at the shopping centre when shots first rang out, and it was his tweets, captured below, that first informed many of the violence in downtown Toronto.

Our thoughts are with the victims of today’s awful incident.
