Yup.
From US Dept of Justice:
"Today homicide is the leading cause of death among young Black men, and contributes significantly to the shortened life-span of the Black male. In about 80-90% of the cases, the Black victim was killed by another Black, and about 52% of the murder victims were acquainted with their assailant."
