ANTELOPE -- There is heartbreak and regret as loved ones mourn the death of Jessica Chavez.
Investigators say the 28-year-old's ex-boyfriend followed her home then shot her in the head last Wednesday in Antelope.
Days later he killed himself.
"This could have been stopped, we could have saved her," said Shay Danielle.
Speaking at a vigil on Sunday, Chavez's best friend and roommate said she knew about the couple's physically and emotionally abusive relationship. She said Wednesday night Gildardo Ramos followed Chavez home from work at Comfort Inn in Rocklin then killed her in front of her home.
"She should have moved out. I feel guilty," said Danielle.
Danielle tells FOX40 Chavez attempted to get a restraining order against her ex-boyfriend last Tuesday.
The Placer County Sheriff's Department said Ramos was arrested back in October on a domestic violence charge. He appeared in court on Monday, was arrested and posted bail. Two days later Chavez was killed.
"This is s person who chose to use the most extreme form of violence to get their own way, and this is the reality of domestic violence," said Julie Bornhoeft, chief development and marketing officer with WEAVE.
Bornhoeft says in cases like these, women can seek protection in temporary shelters, and friends and family should always step in when they see the warning signs of an abusive relationship.
"If you suspect something and you're concerned, odds are you're only seeing a small portion of it," said Bornhoeft.
While it's too late for Chavez, some of her friends are pushing for change.
They've created and online petition on change.org. They're trying to stop domestic violence offenders, like Ramos, from being released on bail without house arrest.
The family's pastor released a statement thanking the community and expressing support for the petition.
"Her family is supportive of these, or measures like these, that will offer significant protection to potential victims in the future. Even the possibility of naming it Jessica’s Law would serve to preserve her memory as one who cared deeply about others," said Bob Anderson.
