Police identified the two students as 12-year-old Sariah Sayasit and 14-year-old Richard Wilson. Sayasit was a student at Delta Sierra Middle School, while Wilson went to Bear Creek High School.
Dozens of family members and friends left candles and shared memories of the two students during a memorial at the crash site on Saturday.
“She was pretty, smart, really helpful at home,” Sayasit’s grandmother, Kristina Sayasit, told FOX40. “I wish I could see her when she left, stop her, but I didn’t know.”
“He was my brother. I was always together with him,” Wilson’s friend Anakin Salazar told the outlet. “I was just talking to him and now he’s gone out of my life."
Officials say the van had 10 people inside when the driver lost control of the 2006 Toyota Sienna and veered to the left of the roadway before driving into White Slough on Nov. 22.
The outlet reported that some of the teens weren't wearing seatbelts and the 17-year-old driver did not have a license.
Officials added that alcohol didn't seem to play a role in the crash.
“I don’t know why the mom let her drive the van and pick up all the kids,” Sayasit told FOX40.
The eight other teenagers in the van were sent to local hospitals with minor to moderate injuries, including hypothermia from being partially submerged in the cold water. A few have already been released.
The cause of the crash is under investigation, while a GoFundMe page has been set up for the family of Sayasit.
"Everywhere she went she came with the biggest smile and warm heart. She was the third of 5 children in the family," said the GoFundMe page. "She is survived by her father, grandmother, three sisters, one brother and she was loved by many. Rest in Paradise sweet baby girl. God has gain[ed] a beautiful angel."
