The F.B.I. data released Monday showed that 23.3 percent of murder victims were slain by family members, and 54.7 percent were killed by acquaintances, while only 22 percent were murdered by strangers. Of last year’s homicides, 9,484 involved firearms, 6,755 of which were handguns, the F.B.I. said.
In each of the four violent crime offenses, the 2008 rates were down from 2007. Murder and non-negligent manslaughter dropped 3.9 percent; aggravated assault declined 2.5 percent; forcible rape declined 1.6 percent; and robbery was down 0.7 percent. The figures are based on offenses per 100,000 people
