Wildfire victims’ families urged to give DNA
SACRAMENTO, Calif. — Authorities are using a powerful tool in their effort to identify the scores of people killed by the wildfire that ripped through Northern California: rapid DNA testing that produces results in just two hours.
The system can analyze DNA from bone fragments or other remains, then match it to genetic material provided by relatives of the missing. But the technology depends on people coming forward to give a DNA sample via a cheek swab, and so far, there are not nearly as many volunteers as authorities had hoped for.
As of Tuesday, nearly two weeks after the inferno devastated the town of Paradise and surrounding areas, the number of confirmed dead stood at 79, and the sheriff’s list of those unaccounted for had about 700 names.
But only about 60 people had provided samples to pop-up labs at the Butte County Sheriff’s office in Oroville and an old Sears building in Chico, where the Federal Emergency Management Agency set up a disaster relief center, said Annette Mattern, a spokeswoman for ANDE, the Longmont, Colorado, company that is donating the technology.
“We need hundreds,” Mattern said. “We need a big enough sample for us to make a positive ID on these and to also give a better idea of how many losses there actually are.”
Families hesitant: Confusion and conflicting information, the inability of relatives to travel to Northern California and mistrust of the government may be contributing to the low number.
Tara Quinones hadn’t heard anything from her uncle, David Marbury, for eight days before she drove north from the San Francisco Bay Area to give a sample Friday. A worker used a small tool to scrape her cheek, took three swabs of skin and asked her detailed questions about who she was looking for and their relationship.
The uncle’s landlord confirmed his house burned down with his vehicle still in the garage, but Quinones had no idea if any remains were found. Marbury’s name keeps going on and off the ever-changing list of the missing.
“I did it just to be proactive,” Quinones said Monday. “This is the one way I could contribute to helping find my uncle.”
Some of those who have given DNA came forward, like Quinones, after learning about the identification effort in their desperate search for a loved one, others after the sheriff’s office called to say that remains that probably belonged to a family member had been found.
Mattern declined to say Tuesday how many victims ANDE’s technology has helped identify. Sheriff Kory Honea’s office did not immediately respond to requests for comment.
The fire was 70 percent contained Tuesday. Rain in the forecast for Wednesday through Thanksgiving weekend could aid in fighting the fire but could also bring flash floods and complicate efforts to recover remains.
Once DNA is extracted from the remains, it is placed in a vial that goes into a black machine that looks like a bulky computer printer. It takes just two hours to process the material and get a DNA profile; traditional methods can take days or weeks. If a relative’s DNA is already in the system, a match will pop up right away.
Mattern said it has been surprisingly easy to get DNA from remains, despite the devastating damage done by the flames.
“We went in with pretty measured expectations, we didn’t know what we were walking into,” she said. “We have a tremendous database now of the victims of the fire.”
Under contract: ANDE won a contract in 2009 to do research and development for federal agencies, and the company’s technology has been used in pilot programs for several years. Over the summer, it won FBI approval for use in accredited labs. Law enforcement agencies in Utah, New York and Miami have used the technology, as has the military.
This is the first time ANDE has helped identify victims after a natural disaster. The company has donated seven machines and about a dozen workers to the effort.
