Michelle Fournier's ex-husband, 42-year-old Scott Dekraai, remains behind bars, accused in the shooting spree at Salon Meritage.
Hundreds gathered at Cottonwood Church in Los Alamitos to remember the 48-year-old, who had worked as a hair stylist at Salon Meritage for more than a decade.
"She had a heart of gold, and a real true friend to anyone that knew her," said Pam Wilson, a family friend.
Dekraai was arrested minutes after the shooting. The district attorney has said he plans to seek the death penalty against him.
In court documents, Fournier alleged that Dekraai physically abused her during their marriage. They divorced in 2007 and were involved in a custody dispute over their young son since then.
The two had just attended a court hearing the day before the shooting rampage.
Fournier leaves behind her family, which includes three children, and a lot of friends.
"She's just a bubbly, wonderful, fun, fun person, and we're really going to miss her," said Robyn Juhasz, another friend.
The program for the memorial service said Fournier's family would like to thank the community of Seal Beach for their love and support.
On Monday, dozens of businesses in the Bay City Center, a Seal Beach shopping center, will donate a portion of their proceeds to the families of the victims.
Also on Monday night, the Seal Beach City Council will be given an update on the emergency response to the salon massacre.
Dekraai appeared in court on Monday afternoon to be appointed a new attorney. He's charged with eight murders, and one attempted murder in the case.
Dekraai was originally represented by a private attorney. But he told the court that he can't afford one, so he was given a public defender.
