The parents, who had been married for nearly 13 years, made the three-hour drive to the coast every year from Yreka to celebrate Jessica’s birthday, reports said.
They were just a few miles from the town of Hiouchi when the accident occurred.
They are survived by five children, who range in age from 8 to 24. They are Megan, Evan, Casey, Allie and Chelsea, KDRV-TV reported.
A GoFundMe was established and so far has raised more than $238,000 for their care.
“This was a shocking and unexpected event, and the tragedy of this accident makes it difficult to accept as real,” Amanda Maffei, a cousin of the deceased, wrote on the page. “These 5 children are now left without parents and are facing a lifetime of expenses.”
Maffei said the older children would likely now have the responsibility of caring for their younger siblings.
“I think that they’re going to find strength within each other,” she said, according to reports. “They’re going to look out for each other and, you know, just the generosity of so many different communities and the support that they’ve received. I’m hoping that they find strength in that as well.”
The accident remains under investigation.
