Black murders account for all of America's clearance decline


Declining homicide clearance rates for African-American victims accounted for all of the nation’s alarming decline in law enforcement’s ability to clear murders through the arrest of criminal offenders, according to a new study of data compiled by the nonprofit Murder Accountability Project (MAP).

Reported clearance rates for the other three races counted in the Supplementary Homicide Report – whites (which includes ethnic Hispanics), Asians and Native Americans – actually improved slightly over the period from 1976 through 2017.

The Federal Bureau of Investigation’s Criminal Justice Information Services Division in Clarksburg, West Virginia, has estimated the nation’s homicide clearance rate for many years and found up to 90 percent of murders were cleared through the arrest of offenders in the mid 1960s, a rate that steadily declined until reaching 61 percent in 2017. This decline in clearance rates has been widely observed for many years.

But the Murder Accountability Project's study found declining clearance rates exclusively occurred among homicides of black victims based upon offender-identification data found in the Supplementary Homicide Report (SHR) from 1976 through 2017. Clearance rates for all other races improved.


This racial divide occurred in every region of the nation and in most communities, regardless of size. Major urban centers, suburban neighborhoods, rural counties and tiny cities all generally experienced a large decline in the rate at which black homicides are solved through arrest.

An analysis of the many murders of Samuel Little

Convicted serial killer Samuel Little in recent months has confessed to law enforcement that he’s strangled as many as 90 women in at least 19 states – a criminal career that would represent the largest homicidal series in U.S. history.

Little's confessions represent less than 3 percent of the 3,150 unsolved female strangulations reported by local police to the FBI over the past 42 years. Yet the location of his claims match many of the highest geographic concentrations of unsolved strangulations. 

California leads the nation with a reported 587 unsolved female strangulations and also has the largest number of cases claimed by Little. He was convicted in 2014 for the murders of three California women and later confessed to 16 other California victims whom police have yet to match to specific homicide cases.

According to the Murder Accountability Project’s serial-crimes detection algorithm, the nation’s largest local cluster of suspicious strangulations occurred in Atlanta with 133 female suffocations, of which 100 were unsolved at the time the Atlanta Police Department reported case information to the FBI. Georgia authorities are investigating Little’s claims of killing seven women, including three victims in Atlanta.

The Bureau of Justice Assistance in collaboration with the FBI reports authorities – through "confirmed forensic linkage" of DNA and other physical evidence – have corroborated 34 of the murders to which Little has confessed and identified an additional 24 cases for corroboration. Even if only those 58 cases are confirmed, Little would surpass the 48 victims for which "Green River Killer" Gary Ridgway was convicted in Seattle.

Police fail to report infanticides and elderly murders

Police and sheriffs’ departments frequently fail to report homicides of infants and elderly Americans to the U.S. Department of Justice, a troubling finding by the nonprofit Murder Accountability Project based upon a comparison of crime data given to the FBI and mortality records reported to the Centers for Disease Control and Prevention.

MAP’s study of 297,816 homicides reported by medical examiners and coroners from 2000 through 2016 and 272,082 homicides in the FBI’s Supplemental Homicide Report for the same period found a significant age bias. America’s youngest and oldest homicide victims are the least likely of any age cohort to be reported by police to federal authorities.


Medical authorities documented 5,261 cases of infanticide while local law enforcement reported only 3,799 infant homicides committed from 2000 through 2017, which means nearly 28 percent of infanticides were not reported to the nation’s official crime record. This makes infanticide the least-reported among all age cohorts for murder. The next-lowest-reported age group were for victims 65 or older, of which police failed to report more than 15 percent.

Reporting rates for infanticide vary enormously by state and by county, reflecting the individual policies of local and state authorities. Police in seven states actually reported more infant murders than were documented by medical authorities, although these differences were quite small. States where police outperformed medical authorities were: Alaska, Arizona, California, Maine, Missouri, Nevada and New Jersey.


But police in other states failed to report hundreds of infant killings. Among the states with the largest numbers of unreported infanticides were: Illinois, Florida, Georgia, North Carolina, Ohio, Michigan, Texas, Alabama, Indiana and Pennsylvania.

Update: Investigation of Atlanta strangulations

Former Atlanta prostitute Susan Drew vividly recalls the multiple deaths of sex workers in the 1990s, a time when city officials warned the press not to declare that the homicides might be the work of serial killers. "People were dying left and right. We knew!" Drew told WXIA-TV, the NBC affiliate in Atlanta. She believes she was also attacked by a likely serial killer.

Veteran WXIA investigative reporter Brendan Keefe is leading a team examining 133 female strangulations in Atlanta stretching back to the 1970s, including 40 killings before and after the 1996 Atlanta Olympics. These cases represent the nation's largest cluster of suspicious homicides, according to a computer algorithm developed by the Murder Accountability Project to spot victims of serial murder among FBI computer files. Dozens of strangulations remain unsolved in the city.


WXIA continues an investigation begun in late 2017. Among the cases reporters are reviewing is the October 19, 1994 murder of Valerie Payton, 39, found with a note near her body that taunted police: "I'm back in Atlanta" and signed by "Mr. X." Michael Harvey was eventually identified through DNA evidence and convicted, although he was prosecuted for only one murder.


"Most police administrators on the higher end would rather eat glass than say, 'We have a serial offender out,'" said Danny Agan, former Atlanta homicide commander who headed the city's famous "Hat Squad" of detectives. Agan agrees that there may be unresolved serial murders.

New study of unsolved female murders in Cleveland


Reporters from WKYC-TV and Cleveland’s The Plain Dealer newspaper have collaborated to review recent unsolved homicides of women and asked the Murder Accountability Project to review their data on 61 unsolved killings going back to 2004.

The review found that 34 of these women were killed by gunfire, 10 by blunt force, 9 by strangulation and 8 by stabbing. Slightly more than 44 percent of Cleveland’s unsolved female homicides were committed through means other than firearms, while the national average for such killings is 29 percent.

Studies of known victims of serial killers consistently show that serial victims are disproportionately female and killed by strangulation, stabbing or blunt force.

Women in Cleveland who perished through these more personal, hands-on methods of killing varied in several statistically significant ways from the city’s women who died from gunfire. They were much more likely to have a history of prostitution, to be 40 years old or older and to be white or Hispanic.

Here are the percentages: Women with a history of prostitution were killed by hands-on methods 77% of the time, compared to 35% for women with no such history. Only 32% of women under 40 died from these personal killing methods compared to 62% of women 40 or older. Among white or Hispanic women, 79% died from the more intimate methods of killing, compared to 34% of African American victims.
