There was an impressive turnout, especially for a Friday night before a three day weekend, but these two victims touched a lot of people here in a Vallejo strip mall where they worked. Their customers say they were always smiling and instead of customers, they really consider themselves friends.
Their murders have made headlines throughout the Bay Area all week, but the loss of Tran and Sales is very personal for many in Vallejo.
"Let us all remember Jenny and Rick, not for how they died but for how they lived," said Tran's co-worker Sandra Le.
Tran was known as Jenny to her co-workers and clients at Devyn's Salon where she cut people's hair for a living, but she was also a friend. Some say she was so warm, wonderful, and will be greatly missed.
Ricardo worked as a security guard at Wells Fargo Bank.
"...And Ricardo...what a wonderful man. He always had a smile and so gracious, so we're going to miss them both," said customer Deanie Richards.
Police believe Tran's boyfriend, Efron Valdemoreo, murdered Ricardo because he thought Ricardo was getting involved with Tran. They also believe Valdemoro strangled Tran before he was shot to death in a confrontation with police.
"It was senseless, the violence was senseless, I still don't even know why it happened," said customer Gus Ejercito.
Tran's co-workers organized Friday night's vigil for the two victims and more than 100 people attended.
"What they represented was just true friendship. That's what will be missed the most and that's why all these people are out here," said Ejercito.
Tran had four sons, ranging in age from 14 to 21. Her friends have set up a fund for the boys and collected money for them at the event. They say Tran was a devoted mother.
