Black on white crime doesn't fit the liberal narrative and the Denver Post is basically just a liberal advocacy publication disguised as a "news" publication. 

Other race related issues you'll never find in the Denver Post are the illegitimacy rate among American blacks and its relation to crime and incarceration rates.
The Denver Post will never publish any articles on why, if "white privilege" is a phenomenon, do American Asians enjoy the highest average level of income in the U.S. 
It will never publish any articles on the excessively high black on black homicide rate either. 

Why? Because the Denver Post's job is not to inform its readers, it's job is to influence its readers with leftist ideology.
