An Analysis of Data on Rape and Sexual Assault

NCJ-163392 Revised Feb. 1997:

Sex offenses and Murder:
After the latter half of the 1980's, the percentage of all murders with known circumstances in which investigators identified rape or another sex offense as the principal circumstance of the murder has declined from about 2% of murders to less than 1%.
Between 1976 and 1994 there were an estimated 405,089 murders in the United States. Of these, the circumstances surrounding the murder are known in 317,925, or 78.5%. Among the cases with known circumstances, an estimated 4,807, or 1.5%, were classified as involving rape or another sex offense. (Note: Over 18 years)

Offenders in sexual assault murders are about 6 years younger on average than other murderers. Youth under 18 have accounted for about 10% of the sexual assault murders since 1976.
