No need to speculate, the data are readily available.
And you are correct. In 2012 there were 48 feloniously killed.
And from a post further down, it looks like 38 tops for 2013—some of the vehicular stuff is fuzzy.
(And I’d argue that taking more precise data from a portion of a period which is random and not cherry picked isn’t speculating, but, when done with a margin of error in mind, estimation.—If you can come up with stats for the full five and a half years it would be great.)
