Olivia Newton-John Was Haunted by Patrick McDermott’s Mysterious Disappearance, Author Claims

Late pop icon Olivia Newton-John remained haunted to her grave over the disappearance of her boyfriend, according to a new biography — even though the National Enquirer was first to reveal secret government documents proved her “dead” beau faked his drowning.

Her on-off lover Patrick McDermott boarded a charter fishing boat for an overnight trip off the California coast but had vanished when the ship returned to dock on July 1, 2005.

“Olivia said at one point that he would haunt her forever because nobody would ever really know what happened,” said Matthew Hild, author of the book A Little More Love, about Olivia, per Fox News Digital.

“To this day there are reports that Patrick McDermott is believed to be alive in Mexico.

“But what she finally told one of her closest friends was, ‘I don’t believe that. I believe he was killed. I think he drowned.’ And I don’t believe she ever really made peace with it.”

At the time of McDermott’s disappearance, the beloved Grease star — who died at age 73 in August 2022 after battling breast cancer — used her celebrity clout to plead for information about her missing lover.

The media firestorm prompted an extensive search by the U.S. Coast Guard Investigative Service (CGIS) — officially closing with a November 2008 report that McDermott “most likely” drowned.

But as the Enquirer reported in our issue dated Feb. 2, 2015, unearthed government papers revealed the CGIS kept the files on McDermott open after a routine check revealed the State Department had him on the “Deadbeat Parent Lookout” list to “prevent him from obtaining a future passport.”

Investigators began to suspect McDermott, a lighting technician who was $35,000 in debt and owed child support, had vanished for financial reasons.

The Coast Guard documents also revealed Olivia and McDermott were taking a break, but she hoped to rekindle their on-off relationship of nine years.

The hidden CGIS report — obtained by the Enquirer through a Freedom of Information Act request — revealed McDermott had been spotted at least a dozen times in locations ranging from Alberta, Canada, and Cabo San Lucas, Mexico, to the tip of Baja California.

CGIS investigators have also chased down numerous “sightings of [McDermott] in the United States and Mexico.”

In 2009, the Coast Guard issued a statement saying the agency was “not actively investigating the case.”

That same year, Olivia said, per Fox: “I think there will always be a question mark. I don’t think I will ever really be at peace with it.”
