The Oregon State Police announced this morning that it had finished processing a backlog of more than 5,000 SAFE kits—that stands for Sexual Assault Forensic Evidence kits, otherwise known as rape kits—thanks to a 2016 law passed in the Oregon State Legislature.

Before 2016, Oregon police agencies only processed SAFE kits when they determined them potentially helpful in an open investigation—meaning many sexual assault survivors reported their experiences and went through the invasive process of DNA collection, only to have those kits sit in storage, untested, for years. That changed with the passage of Senate Bill 1571, which mandated that all SAFE Kits be processed in a timely manner.

In Multnomah County alone, nearly 3,000 SAFE kits needed to be tested. A team made up of the Portland Police Bureau, Gresham Police Department, Multnomah County Sheriff’s Office and the Oregon State Police Forensic Laboratory had already started the process of securing funding for testing those SAFE Kits in 2015, when they applied for a grant from the New York County District Attorney’s Office. They received nearly $2 million in funding that year, and finished clearing the backlog last month.

Earlier this year, the Portland Police Bureau reported that evidence from the SAFE kit backlog helped them to convict a man on two counts of sex abuse. The case had first been reported to police in 2006.

According to PPB spokesperson Chris Burley, the backlogged SAFE kits helped move four other sexual assault cases forward.

Steven Tubbs of Portland was found guilty of two counts of first-degree rape and two counts of first-degree sexual abuse earlier this year, following the testing of a SAFE kit that had been collected in 2010. Curtis Williams also was found guilty of rape this year thanks to a kit from 2011.

Another case is currently in trial and a fourth is pending trial, Burley told the Mercury.

Though Oregon’s backlog of SAFE Kits was significant, the problem is by no means isolated to this state. End the Backlog, a nonprofit funded by “Law and Order: Special Victims Unit” actress Mariska Hargitay, estimates that there are still hundreds of thousands of untested kits collecting dust in police storage units across the country.

According to End the Backlog, Oregon joins just two other states—Colorado and Ohio—that have completed testing their backlogs.
