Backlogged Rape Kits A “Gold Mine” of Data on Rapists and Victims

New data collected from the testing of nearly 5,000 forgotten and backlogged rape kits in Cuyahoga County, Ohio, challenges conventional wisdom about rape.

The testing by the Cuyahoga County Sexual Assault Kit Task Force — which has led to more than 250 convictions — has also given unprecedented information on hundreds of sexual assaults committed between 1993 and 2010.

This is changing how law enforcement and academics view and prosecute rape, according to researchers at the Begun Center for Violence Prevention Research and Education at Case Western Reserve University in Cleveland.

The research team discovered serial rapists are far more common than previous research suggested, a finding that could change how sexual assaults, including so-called acquaintance rapes, are investigated. They are also learning more about how rapists operate and their victims.

“By working together, we can help change the way sexual assaults are investigated and how the system and society view sexual assaults, victims, and offenders,” said Daniel J. Flannery, the Dr. Semi J. and Ruth W. Begun Professor, director of the Begun Center, and co-lead researcher of the Cuyahoga County Sexual Assault Kit Pilot Research Project. “We have an historical opportunity and obligation to make a difference.”

“These rape kits have been the greatest gold mine of information and leads for law enforcement that I have seen in my four-decade career,” said Cuyahoga County Prosecutor Timothy J. McGinty. “We are going to end up prosecuting a thousand criminals, and that will make our county significantly safer. But we also want to learn from mistakes that created this backlog and never allow them to be repeated.”

“The thousand or more cases we expect to solve will help us understand the behavior of these career criminals so that police can more effectively and promptly investigate and prosecute rapes. This task force will prevent new victims from being attacked because these criminals will be in prison,” McGinty added.

Among the research team’s early findings:

Serial rapists are far more common than previous studies had suggested. Of the 243 sexual assaults studied, 51 percent were tied to serial offenders, who generally had more extensive and violent criminal histories than one-time sexual offenders.

“Our findings suggest it is very likely that a sexual offender has either previously sexually assaulted or will offend again in the future,” said Rachel Lovell, a senior research associate at the Begun Center and co-leader of the Cuyahoga County Sexual Assault Kit Pilot Research Project.

“Investigating each sexual assault as possibly perpetrated by a serial offender has the potential to reduce the number of sexual assaults if investigations focus more on the offender than on single incidents.”

Rapists have long criminal histories that often began before their first documented sexual assault and continued after it.

An overwhelming majority of both serial and one-time sexual offenders had felony-level criminal histories: 74 percent of all serial rapists had at least one prior felony arrest and 95 percent of them had at least one subsequent felony arrest. Among one-time sexual assault offenders, the figures were 51 percent and 78 percent.

Among the serial sex offenders, 26 percent had a prior arrest for sexual assault and 60 percent had a subsequent arrest for sexual assault.

“These are one-man crime waves,” said McGinty. “And now that we realize this, we cannot allow these kits to sit on shelves untested in the future. They hold the keys to identifying and convicting dangerous criminals.”

Serial and one-time rape suspects exhibited different behaviors during their crimes.

For example, sexual assaults committed by serial offenders more frequently involved kidnapping victims and then verbally and physically threatening them, often with weapons. However, sexual assaults committed by serial offenders less frequently involved restraining victims and injuring them in order to complete the attack. One-time offenders were actually more likely to punch, slap, hold down or restrain a victim, according to the findings.

Serial offenders were more likely to commit sexual assault outdoors, in a vehicle, or a garage while a one-time offender was more likely to attack in his own house, or the house of the victim or a third party. Serial sexual offenders tend to attack in the same type of location. According to the analysis, 58 percent of serial offenders commit all of their crimes in the same type of setting.

One-time offenders are more likely than serial offenders to commit sexual assaults with others, such as participating in gang rapes.

Serial offenders were more frequently strangers to their victims compared to one-time offenders.

Half the serial offenders assaulted only strangers, but fully a third of them had a mix of known and unknown individuals among their victims. This underscores the need to thoroughly investigate acquaintance rapes, because of the possibility those offenders have or will engage in assaults against strangers, too.

Also of note is that even in cases of assaults by strangers, victims frequently provided some kind of identifying information to police, such as a partial name, a nickname or a license plate.

Most victims initially cooperated with police. The drop-off came after the first reporting encounter between investigators and victims — 69 percent did not respond to further attempts to be contacted by police.

Victims in the cases studied — all but three of them female — ranged in age from 2 to 70, with an average age of 26. Nearly 70 percent were African American, a reflection of the neighborhoods where the incidents documented in the backlogged rape kits took place.

As researchers move forward with this project, they hope to explore additional topics, including a deeper understanding of different types of serial and one-time offenders, the characteristics of victims that significantly impact an investigation and prosecution of a rape allegation, and how communication between police and victims affects continued victim cooperation.
