Homicide deaths accounted for the largest disparity among young adults, and were 20 times as high for black males and six times as high for black females when compared to their white counterparts. Homicide was the main cause of death for young black men and reduced the overall life expectancy for all black males by more than half a year.

and exactly the data you're asking for, from the FBI:
2870 black victims of homicide
543 from white offenders

3499 white victims of homicide
2854 from white offenders
533 black offenders
Blacks die at the hands of blacks; as whites die at the hands of whites. Families and friends are funny that way.
