In a jaw-dropping development to an already disturbing case, new details have emerged revealing that British businessman Mark Raymond Gibbon, 62, was allegedly involved in a two-year affair with his daughter-in-law, Jasmine Wyld, 33, prior to his attempt to drown her during a family vacation in Florida. Sources close to the family claim that Gibbon’s son, Alex, caught the pair in bed together, leading to the breakdown of family relationships long before the violent incident at Solterra Resort.

The affair reportedly began after Wyld’s divorce from Alex Gibbon, Mark’s son, shattering the family dynamic and sowing seeds of deep-seated resentment. According to reports, Alex walked in on his father and ex-wife in a compromising position at the family home in Beaconsfield, Buckinghamshire, an event that precipitated years of tension and estrangement.

This bombshell comes just days after Gibbon’s arrest on August 3 at the luxury Solterra Resort in Davenport, Florida, where he is accused of attempting to murder Wyld by repeatedly forcing her head underwater during a heated argument in the vacation home’s swimming pool. The dispute, initially described by authorities as centering on Gibbon’s grandchildren or his will, may now be linked to lingering bitterness from the illicit relationship.

Polk County Sheriff Grady Judd, who previously commented on the case, has not yet addressed these new allegations publicly. However, investigators are reportedly examining the family’s history, including the affair, as potential motive for the attack. Wyld, who sustained minor injuries during the struggle, told detectives she feared for her life as Gibbon held her down, preventing her from breathing.

Adding to the tragedy, Wyld’s 9-year-old daughter—Gibbon’s granddaughter—witnessed the assault and bravely jumped into the pool to intervene, only to be shoved away by her grandfather. Neighbors from a nearby rental property overheard the screams and called 911, leading to Gibbon’s swift arrest.

Extended family members said they believe Mark Gibbon has been having an affair with Jasmine Wyld, his former daughter-in-law for the last two years – causing a huge family divide

Gibbon, a successful lighting technician and owner of MRG Lighting, who has worked with celebrities like Ed Sheeran and Sam Smith, admitted to pushing Wyld underwater but denied intent to kill. He claimed alcohol consumption fueled the argument. Despite the new revelations about the affair, Gibbon remains held without bond at Polk County Jail, facing charges of second-degree attempted murder and two counts of battery. His next court appearance is set for September 9, 2025.

Friends and neighbors back in the UK expressed shock at the allegations. One acquaintance described Gibbon as a “family man” whose life unraveled after the affair was exposed, leading to isolation from his son.

As the investigation continues, this case underscores the devastating consequences of hidden family secrets erupting into violence. Neither Wyld nor Alex Gibbon has commented publicly on the affair claims, and authorities urge anyone with information to contact the Polk County Sheriff’s Office.
