Abstract In 1960 when the homicide rate in the United States was 9,110 the clearance rate stood at 92% (FBI, 1997), accounting for the clearance of 8,382 murders (Harris, Thomas, Fisher, & Hirsch, 2002; Regoeczi & Miethe, 2003; Litwin, 2004). Unfortunately, by 2002 the reported number of homicides solved and cleared by arrests had dipped to 62% (FBI, 2002). The unsolved rate in 2002 in the United States represented a 76% increase since 1960. The increase in unsolved/ uncleared homicide offenses has grown during the last 45 years in spite of the advances in investigative technologies, educational and training enhancements for investigators, and operational emphasis by law enforcement agencies towards community policing. The article explores issues and inferences from current research regarding reasons for the decline in the past decades in the solving of homicides in the United States. doi:10.1300/J460v02n03_05
