The collision occurred in the 7800 block of Evergreen Way around 6 p.m., Everett police spokesman Aaron Snell said.
The Snohomish County Medical Examiner's Office on Wednesday identified the child as Josiah A. Alves, 7. He died from head injuries.
Josiah was a second-grade student at Madison Elementary School, Everett School District officials said.
Extra counselors were at the school Wednesday and letters were sent home to parents in the afternoon, school district spokeswoman Mary Waggoner said.
Josiah's older brother is a third-grader at Madison and a younger sister attends a preschool class.
In a letter to parents, Madison principal Mark Toland told parents they should talk to their children about the sad news.
"You do not need to have answers to all their questions," he wrote. "Just acknowledging that sometimes there are no answers is all that is required. Let them know that you are listening, and care too."
Initial reports indicated the black BMW carrying Josiah was being driven erratically southbound on Evergreen Way at a high speed when it clipped another southbound vehicle. The BMW spun and went into oncoming traffic where a northbound minivan collided with it, Snell said.
The drivers of the BMW and minivan were taken to Providence Regional Medical Center Everett.
The driver of the minivan is a Marysville woman, 75, who was believed to have injuries that weren't life threatening.
The BMW's driver was identified as an Everett man, 30, who was the boy's guardian. He was treated and released from the hospital.
"Physical evidence from the incident has been collected and is currently being processed," Snell said. "No charges have been made in this case and detectives continue to investigate the cause of the collision."
It is unknown if alcohol, drugs or health concerns played a part in the incident, Snell said.
Both northbound and southbound Evergreen Way were closed for almost two hours Wednesday to investigate the scene and clear the vehicles.
