I visited your link and could not see a matching statistic.
Filtering by "unarmed" and hovering over "Race" I got a count of 19 White, 15 Black, 4 Hispanic.
I then also had a quick look at the article for "Brett Luengo", [0] (White) which states i.e. "Luengo attacked a woman first..." etc. etc.; I mean it goes on for quite a while. So seems like there's a big variation in the definition of "unarmed man" shooting that doesn't preclude other kinds of violent or aggressive activity/indications.
Looks to me like the statistics are not really telling the whole story there so maybe that's why you don't hear them "covered in the national news".
