How many brutal crimes occur every week, only a few a year ever get national attention.
Trying to find patterns or reasons for the coverage is probably futile, certainly looking at individual cases is pointless. There's not enough rhyme or reason to it.
Remember the "Year of the Shark" a few years ago? Turns out there were FEWER than average shark attacks that summer. Why did the attacks get so much coverage that year? Who knows. Probably some network exec's daughter knew someone whose cousin's babysitter's sister was attacked.
What are the actual numbers of racially motivated crimes? The latest FBI statistics available are below. This seems like a difficult thing to get accurate numbers on, but I'll trust the FBI to be in the ballpark:

Racial Bias
Among the single-bias hate crime incidents in 2005, there were 4,895 victims of racially motivated hate crime.
* 67.9 percent were victims of an anti-black bias.
* 19.9 percent were victims of an anti-white bias.
* 5.3 percent were victims of a bias against a group of individuals in which more than one race was represented (anti-multiple races, group).
* 4.9 percent were victims of an anti-Asian/Pacific Islander bias.
* 2.0 percent were victims of an anti-American Indian/Alaskan Native bias.
(Based on Table 1.)
An analysis of available race data for the 6,804 known hate crime offenders revealed that:
* 60.5 percent were white.

* 12.3 percent were unknown.
* 5.2 percent were groups made up of individuals of various races (multiple races, group).
* 1.1 percent of known offenders were American Indian/Alaskan Native.
