Fullerton Triple Homicide Leaves Community In Shock

FULLERTON (CBSLA.com) — Two men arrested for the murders of a Fullerton couple and a family friend knew the victims and their teenage daughter, and all were members of the "furry" community, according to friends.

Jennifer Yost, 39, and her husband, Christopher Yost, 34, were found dead Saturday in their Fullerton home along with family friend Arthur "Billy" Boucher, 28.

Frank Felix, 25, Joshua Acosta, a 21-year-old soldier at Fort Erwin, and a juvenile have been arrested in connection of the murders.

The suspects were scheduled to be arraigned Tuesday.

Matthew Sawyer, the ex-boyfriend of the couple's 17-year-old daughter, Katlynn Yost, said she met the two suspects through the "furry" community - a group of people who enjoy dressing up as animal characters.

"The two other suspects that were arrested - they were friends with not only Katy but the family and myself," Sawyer said.

Melinda Giles said she met Jennifer Yost at a "furry" event last year.  She said Jennifer Yost told her several weeks ago that she had forbidden Felix from seeing her daughter.

"To protect her daughter, Chris and Jenn were like, `We don't want you to be friends with our daughter anymore,"' Giles said Monday and added that the couple was warm, generous and recently helped her move into her new home. "It is really sad because they didn't deserve that. Those little girls didn't deserve to wake up to dead parents."

Community members were still trying to understand why their neighbors were targeted.

"I want to know what happened," said Angela Major, the mother of victim Christopher "Bubba" Yost. "Somewhere, there was hate. I don't understand it. Bubba hated nobody, ever."

Fullerton police Sgt. Jon Radus would not say if the arrested teen was Katlynn Yost, who was reported missing but later found.

"That said, a 17 year old female juvenile has also been detained in connection with the murders and is in the custody of the Orange County Juvenile Hall," he said.

The arrests Sunday came a day after the Yosts' six-year-old daughter called 911 to report that her parents had died.

She was not harmed. Nor was her nine-year-old sister.

Radus did not disclose a motive but said the victims knew their attackers.

"We hope the quick arrest of these individuals will bring comfort to the community and assist the friends and family of those affected by this unthinkable crime," he said.

At a candlelight vigil held outside the family's home Sunday evening, those who knew the Yosts said they were loving parents and friendly neighbors.

Donna Trice, a former neighbor, said Christopher Yost was an auto mechanic and his wife a stay-at-home mom and jewelry maker.

"There's nothing that can justify what happened and why the parents were taken away from the children," she said.

Neighbors said the family liked to decorate their front yard for Halloween and invited kids to stop for candy and play games.

Friends and relatives of Boucher said he occasionally slept at the house and worked as a hotel custodian.

"He was always standing up for women in his family, me included," his girlfriend Joyce Burchett said through tears. "I'm at a complete loss."

A GoFundMe account was set up to raise money for the victims' funeral expenses and to raise money for the education of the victims' children.
