Yesterday, at around 3 p.m., Brendan reported that the number of gun-related homicides in Seattle this year was 20. It was—yesterday at around 3 p.m.
Now that another of Wednesday's shooting victims has died, it's 21 gun-related homicides for the year so far.
As Brendan already noted:
By this time last year, there had only been three.
However, for a city the size of Seattle, the current murder rate is still relatively low.
