California furry ‘orchestrated triple homicide after becoming obsessed’ with teenage girl he met at convention

It was love at first sight for a 25-year-old dragon-haired man who fell in love with a teenager who called himself Day Dreamer Fox Wolf.

But after her parents banned the two from seeing each other because she was underage, he hatched a twisted plan to wipe them out, a California court has heard.

Frank Felix, 33, who went by the fursona Entey, met then-17-year-old Katlynn Goodwill Yost at a “furry convention” – an event for people who enjoy dressing up in elaborate animal costumes.

Felix knew Katlynn and her parents through the furry community, where her mother Jennifer served as a shoulder that other furries could lean on to help them deal with their problems.

Felix’s accomplice, Josh Acosta, 29, also had a connection to the family and was a well-known ‘Brony’ – a man who is a fan of My Little Pony. DailyMail.com has learned that Felix’s fursona was a dragon.

Prosecutors say Frank Felix, 33, masterminded the 2016 triple homicide. He was escorted to Orange County Superior Court on Wednesday for opening statements

Felix is ​​charged with three counts of murder and faces life in prison without the possibility of parole if convicted.

Acosta was found guilty of all three murders on November 8, 2018, and sentenced to life in prison on December 14 of the same year.

After discovering her daughter’s relationship with Felix, who was 25 at the time, Jennifer, 39, told her to stop seeing him, the court in Santa Ana, California heard.

Her friend Melinda Giles, who is also a furry, told DailyMail.com in 2016: ‘To protect her daughter, Chris and Jenn said, “We don’t want you to be friends with our daughter anymore.”

After their relationship ended, Felix and Acosta, who was then 21 years old and a private first class in the Army stationed at Fort Irwin, hatched a plan to free Katlynn from her parents. the Dagblad reported.

The obsession grew to the point of self-harm after their relationship fell apart. Prosecutors described how, in one instance, Felix cut himself in front of the teen.

In the week leading up to the murder, he allegedly planned their deaths with Acosta via email.

They executed this plan in the early morning of September 24, 2016.

The bodies of Jennifer, her husband Christopher Yost, 34, and their family friend Arthur “Billy” Boucher, 28, were found by their then 6-year-old daughter in their Fullerton home.

Their 9-year-old daughter was also in the house at the time of the murder, but was unharmed.

They carried out their plan in the early morning of September 24, 2016, using Felix's father's shotgun: they cut the security lock with bolt cutters they had purchased that week.

The prosecutor laid out a one-week timeline during opening statements at the Orange County Justice Center that he said showed the killing was premeditated.

They bought bolt cutters, earplugs and shotgun ammunition in Burbank, California.

The prosecutor stated that Felix wrote to an acquaintance: “Maybe I’m helping someone commit a murder.” At the friend’s advice not to go through with it, Felix switched gears and said he was talking about an animal.

They also noted that the defendant was “nervous” in email exchanges with Acosta outlining their plans. In one case, they wrote that whoever opened the front door would be pushed aside or shot.

Acosta was the one who agreed to carry out the murders after Katlynn said she was harassed weekly by her stepfather Christopher. She would also testify about this in 2018 during the trial of the former army mechanic in exchange for immunity.

The 17-year-old let them into the house and was waiting in the car with Felix when Acosta entered the home.

The furry lover also admitted that he knew the children were home and that he planned to leave food for them after they slaughtered their parents, prosecutors said. They also knew that Boucher would be staying overnight, with Felix admitting that he knew there would be a third body by the end of the bloodshed.

Acosta’s defense at his 2018 trial argued that the couple had been manipulated by Katlynn into carrying out the murders. It’s unclear what angle Felix’s defense will take, as they have declined to speak until further into the trial.
