SANTA ANA, Calif. — An Army private and another young man were charged with murder in the slayings of a California couple and family friend who were discovered after the couple's 6-year-old daughter called police.
Army Pfc. Joshua Acosta, 21, and Frank Felix, 25, were each charged Tuesday with three counts of murder, and Acosta also faces possible sentencing enhancements for personal discharge of a firearm causing death, the Orange County district attorney's office said.
Acosta and Felix were friends with the couple's daughter and attended "furry" events where some participants dress up in colorful animal costumes, according to friends and their social media pages.
Prosecutors allege that Acosta was the gunman in the killings of Jennifer Yost, 39, her husband, Christopher Yost, 34, and their friend Arthur Boucher, 28.
A district attorney's statement says the killings occurred when Acosta and Felix entered the Yosts' Fullerton home early Saturday.
An arraignment initially set for Tuesday was postponed until Oct. 28. Neither man has been reachable for comment while being held in jail since the weekend.
The district attorney's office made no mention of a 17-year-old girl who was also taken into custody by Fullerton police in the case.
After the bodies were discovered Saturday, police said Jennifer Yost's 17-year-old daughter, Katlynn Goodwill Yost, was missing. When the teen's arrest was announced, police also said the daughter had been located but did not say whether she was the teen in custody.
Police were summoned to the home Saturday by the couple's younger daughter. She was not harmed, nor was her 9-year-old sister.
Melinda Giles said she became friends with Jennifer Yost after meeting her and her daughter last year at a gathering of "furries."
She said she also saw Felix and Acosta at furry events, and had met Felix at the Yost family home.
She said Jennifer Yost told her several weeks ago that she had forbidden Felix from seeing her daughter.
Giles said Jennifer and Christopher Yost were warm and generous and recently helped her move into her new home.
Boucher was staying with the Yosts at the time of the killings.
Goodwill Yost is a high school senior and member of the Junior Reserve Officers' Training Corps. Her social media pages show she is active in the furry community, where she was known as "Daydreamer," and many photos are posted.
She is seen wearing her military uniform in one, and others show a gray fox-wolf costume.
Felix is from Sun Valley, California.
A wheeled-vehicle mechanic, Acosta has been assigned to Fort Irwin, California, since last October, said Wayne V. Hall, an Army spokesman at the Pentagon. Acosta entered the service in March 2015 and previously was assigned to Fort Lee, Virginia, and Fort Jackson, South Carolina.
Contact information for his family was not immediately available.
