Dozens of friends and family held a candlelight memorial Wednesday at the Vallejo home of a mother and her teenage twins.
Police said they were killed Sunday in a suspicious fire that is now being investigated as homicides. Detectives are still piecing together how the fire started and who may have set it.
Friends and family at the memorial honored Trinh and Tram Tran, and their mother, Mao.
"It's been really heartwarming these past three days to see everyone coming together for them," said Mililani Jimenez, a friend of the victims.
Wednesday's vigil was the third held this week. The girls' former wrestling coach, Jason Guiducci, hosted an event for the Tran sisters on Tuesday.
"They brought so much joy, so much talent and grace, and beauty to our community that's so often needed," Guiducci said.
Family members at Wednesday's memorial said the youngest of the Tran family, an 11-year-old girl who survived Sunday's house fire, is in good condition.
A friend of the family previously told NBC Bay Area the girls' father is out of the country and may have left to Vietnam a few days before the fire. Police have not released any information on his whereabouts.
Detectives have not named any suspects or persons of interest in the case.
Anyone with any information regarding the fire is encouraged to call Detective Yates and Detective Poyser of the Vallejo Police Department Detective Division at 707-648-4080.
