A horrific mass murder-suicide incident was discovered Monday on a rural property near the small town of Henryetta, Oklahoma, in which five teenagers and two adults were all found dead of gunshot wounds.

According to the Daily Mail, one of the bodies was that of 39-year-old Jesse McFadden, a convicted rapist and registered sex offender who was set to stand trial for "sexting" with a minor while in prison several years ago, and is suspected of perpetrating the grisly homicides.

Search for Missing Girls Called Off Following Discovery of Bodies

The victims have been identified as Holly Guess, 35, McFadden's wife, along with her three children Rylee Allen, 17, Michael Mayo, 15, and Tiffany Guess, 13, as well as two of Tiffany's friends, Brittany Brewer, 16, and Ivy Webster, 14.

The Daily Mail reported that friends Brittany and Ivy had left their respective homes on Saturday to spend the night with Tiffany, as had occurred in the past given that nobody in the community was fully aware of McFadden's criminal past -- Guess, who met and married McFadden after he was released from prison in 2020, allegedly only learned of his criminal history a few months ago. The girls were reported as missing after they hadn't returned by Sunday evening.

An Amber Alert for the missing girls was issued and a search ensued but was called off Monday afternoon when law enforcement discovered the bodies on McFadden's property.

Evidence Suggests Murder-Suicide Scene "Staged"

According to Tulsa outlet News on 6, authorities had gone to McFadden's property in search of him when he failed to appear in court that morning for a trial on charges that stemmed from his use of a contraband cellphone while in prison to exchange nude pictures and sexual texts with a minor several years earlier.

Okmulgee Police Chief Joe Prentice said during a press conference that the murders had been committed with a 9mm handgun purchased a year earlier by McFadden's wife, Holly Guess, and that it was unclear what the motive for the killings was due to the fact that everyone involved in the incident was dead.

"I follow the evidence, and the evidence is that Jesse McFadden murdered six people and then killed himself," he stated.

According to the New York Post, Prentice also said, "Without going into a lot of detail, that scene appeared to be staged to me, and that is my opinion based on what I observed," and added, "I think the bodies had been moved from where they were originally killed."

Local reports indicate that the bodies of McFadden, his wife Holly, and her children Michael and Tiffany were found together in one area while Guess' oldest daughter Rylee and the two missing friends, Brittany and Ivy, were found together in a separate area about a quarter-mile away.

Chief Prentice acknowledged during the press conference, "There are questions that will never get answered because the only people that know are no longer here."

Cryptic Texts Sent to Prior Sexting Victim

Though the exact motive remains unknown, local outlet Fox 23 reported that McFadden appeared to have sent multiple cryptic text messages on Sunday night to the formerly underage victim he had previously messaged from prison, for which he was set to stand trial on Monday, that seemed to blame her for his actions.

"I did exactly what I promised I would do when I got out I got a marketing job making great money and was being advanced been there 2 years now and made a great life like I promised I would do with you," he wrote in one text, followed by, "Now it’s all gone."

"I told you I wouldn’t go back," McFadden said in another message and concluded, "This is all on you for continuing this."

McFadden Released from Prison in 2020, Out on Bond Pending Trial

USA Today reported that there are now questions and recriminations swirling about how a "monster" like McFadden could have been released and allowed to live in the small and unsuspecting community in light of his past crimes and pending charges of soliciting sexual conduct with a minor and possession of child pornography that stemmed from the contraband cellphone incident in 2017.

McFadden had been convicted of first-degree rape in 2003 and was sentenced to serve 20 years, of which he served a minimum of 85 percent of the sentence plus credit earned for good behavior and time served, per state statute, that resulted in his release from prison in 2020 and then release from the county jail on $25,000 bond for the pending charges on the 2017 incident.

The outlet noted that it was a bench warrant issued for McFadden's failure to appear in court on Monday that led authorities to his rural property and the grisly discovery of the multiple dead bodies.
