Maria Perez died after being struck while walking Sunday night near Middlefield Road and Beech Street, according to authorities.
Officers said the crash occurred shortly before 10 p.m., and the driver left the scene.
At a roadside vigil on Wednesday, family members remembered Perez as a caring and supportive presence.
"She was a very kind and helping person; she would always be there for all of us and give us advice about anything," said Cindy Perez, the victim's niece.
Perez's sister, Irma Perez, described the loss as devastating.
She said in Spanish that Maria was a loving aunt, family member, and friend who touched many lives.
The family said the emotional toll has made it difficult to process their loss while the driver remains unidentified.

"We really haven't been able to reminisce, at least for me, because of the anger I have inside. We're just really hope everything gets better for our family mentally and physically and that people keep praying for our family," Cindy Perez said.
Family members are also urging changes to improve safety along the busy corridor where the crash happened.
"To put speed bumps because I know a lot of people drive really fast and don't really respect the pedestrians around there," Cindy Perez said.

Street safety advocates echoed those concerns, citing dangerous driving behavior in the area.
"In that intersection people are cutting lanes taking to the shoulder to overtake cars," said Karvin, an advocate for safer streets. "I do think the city council and city staff could dedicate more resources to not just this area but across the city."
Police said the suspect vehicle is believed to be a white truck.
Authorities are asking anyone with information to contact the Redwood City Police Department.
As the investigation continues, the Perez family said they remain focused on seeking justice.
"I just really hope that whoever did it really does come to light and I hope that they feel guilty for what they did because wasn't okay," Cindy Perez said.
