(CNN) -- A recently engaged man who worked with autistic children. His fiancée, who was chaperoning the trip. An admissions counselor dedicated to helping low-income students get into college. A high school football player taking a college tour. And a 17-year-old girl looking forward to an adventure with her twin.
They are among the confirmed dead or those not yet officially identified after a bus carrying dozens of California high school seniors was struck by a FedEx tractor trailer about 100 miles north of Sacramento on Thursday night, authorities said. The crash killed 10 people, including five high school students, three chaperones and the drivers of both vehicles.
The students were traveling from the Los Angeles area for a program at Humboldt State University. They represented 31 Southern California high schools participating in "Spring Preview Plus," which offers low-income and first-generation prospective students a glimpse of college life. Two other buses in the caravan reached the university, where students received counseling.
On Saturday, some of those who died or remained unaccounted for were remembered.
Michael Myvett and Mattison Haywood, chaperones
Michael Myvett, 29, had his fiancée, Mattison Haywood, wear blue heels when he proposed outside the Louvre in Paris late last year.
He loved the shoes and wanted them preserved forever in images from their big day.
"She had no idea that I was going to ask her," he posted on Facebook at the time. "She was mad at me cause I wanted her to wear those shoes and her feet were hurting. I remember her saying, 'omg are you serious'?"
Mattison Haywood, teetered in the heels as Myvett went down on bended knee. He slipped a diamond on her finger.
The couple never made it to their wedding day.
"He was a father figure to both of his brothers," said his cousin, Trinice Sampson. The family was notified of the deaths of both Myvett and Haywood, Sampson said.
"He was one of the first people to graduate college in the family," Sampson said of his cousin. "He is so responsible."
Myvett wanted to be a psychologist and hoped to make an impact on the lives of others, according to his cousin.
His alma mater was Humboldt State, where he was taking prospective students. He also worked with children at the Center for Autism and Related Disorders in west Los Angeles.
He turned 29 last month.
Arthur Arzola, Humboldt State University admissions counselor

"He dedicated his career to that work," said the statement.
It continued, "The campus community extends its deepest condolences to Arthur's family and friends. Words cannot express our sadness, and we are here to support them in any way possible."
On Facebook, Dante Rios, who described himself as one of Arzola's best friends and a groomsman in his wedding, posted photos of a smiling Arzola on his wedding day and other occasions.
"This smile is making Heaven a whole lot brighter today," Rios wrote. "Our angel, Art Arzola, my bro, the most humble and thoughtful person that I have ever known.. There will never be another person like you.. My heart hurts so much to know that I can't... ever hear you laugh, give you a hug, see you dance to Timbaland.."
He added, "But those memories and all of the things we've done together over the last 8 years that I've known you, will be the ones that bring a smile almost as big as yours to my face, man.. I know we will reunite someday, somewhere.."
