"We will release further details as they become available," police said in a statement. "For now, our priority is protecting the victims’ identities as we notify family and complete our investigation."
A handful of people stopped by the crash site Thursday and left flowers. That included Hasan Shaikh, who told NBC Bay Area that he knew the father and that the family lived nearby.

“It was very shocking," he said. "It was very shocking because it’s something that you don’t want to hear, plus it’s the entire family.”
According to Shaikh, the father of the family worked at a high-tech company for about five years with him. Shaikh said the father's spirit will be missed.
“I was always trying to meet you with great energy, so it was always good to talk to him,” Shaikh said.
Pleasanton Unified School District officials did not confirm if the children attended its schools, but said because children were involved in such a crash, it checked in with students and staff.
