Couldn't find what you requested. Perhaps if you are interested you can find the stats.

I did find this interesting tidbit:
n the last decade (since 2000) the homicide rate declined to levels last seen in the mid-1960s
 The homicide rate doubled from the early 1960s to the late 1970s, increasing from 4.6 per 100,000 U.S. residents in 1962 to 9.7 per 100,000 by 1979 (figure 1). (See Methodology for information on rate calculations.)
 In 1980 the rate peaked at 10.2 per 100,000 and subsequently fell to 7.9 per 100,000 in 1984.
 The rate rose again in the late 1980s and early 1990s to another peak in 1991 of 9.8 per 100,000.
 The homicide rate declined sharply from 9.3 homicides per 100,000 in 1992 to 4.8 homicides per 100,000 in 2010.
The number of homicides reached an all-time high of 24,703 homicides in 1991 then fell rapidly to 15,522 homicides by 1999

Note: Data are based on annual estimates of homicide from previously published versions of Crime in the United States. Data for 1989 to 2008 reflect updated homicide estimates from Crime in the United States, 2008. Data for 2009 and 2010 reflect updated homicide estimates from Crime in the United States, 2010.

Number of homicide victims, 1950–2010

The number of homicides increased steadily from the early 1950s until the mid-1970s (figure 2).
Between 1999 and 2008, the number of homicides remained relatively constant, ranging from a low of 15,552 homicides in 1999 to a high of 17,030 homicides in 2006. These homicide numbers were still below those reported in the 1970s, when the number of reported homicides first rose above 20,000 (reaching 20,710 in 1974).
