David Wilcock, the famed paranormal author, YouTuber and a leading figure in the UFO disclosure movement, died Monday in Colorado after apparently taking his own life. He was 53.

Authorities found a man, believed to be Wilcock, armed with a weapon he later turned on himself at a home near Nederland after receiving a frantic 911 call at 10:44 a.m. reporting an “unknown problem,” according to the Boulder County Sheriff’s Office said.

Authorities said the 911 dispatcher suspected the caller was experiencing a mental health crisis.

Deputies arrived to a man outside the home gripping a weapon, which he allegedly turned on himself minutes later, authorities said.

He was pronounced dead at the scene.

A sweep of the home and surrounding property turned up no one else, according to police.

The official cause and manner of death is awaiting confirmation from the Boulder County Coroner’s Office.

The sheriff’s office has not publicly identified Wilcock, whose death was first reported by TMZ.

But Florida Rep. Anna Paulina Luna confirmed Wilcock’s suspected suicide in a post on X Tuesday night.

“We just learned of the tragic passing of David Wilcock,” the Republican wrote. “We are praying for his family and loved ones and the millions of lives he impacted.”

Wilcock, a New York Times bestselling author with roughly 512,000 YouTube subscribers, built his reputation on paranormal claims in books like “The Source Field Investigations,” The Synchronicity Key” and “The Ascension Mysteries.”

He was also a major voice in the UFO disclosure movement, which demands an end to alleged government secrecy over aliens.

Days before his reported death, the social media personality posted on X that he had “some very intense stuff going on” and thanked a long list of donors and supporters, whom he referred to as a “family.”

“My Dear Family, I am not yet sure if I am doing a show tomorrow,” he wrote in the Saturday post.

“I’ve had some very intense stuff going on this weekend. Either way, I want you all to know how much I love and appreciate you! Always remember that the Creator is within — and we live in a loving universe. I am very grateful to you for all of your love, care and support.”

Wilcock, who also had over 61,000 Instagram followers, made his final appearance on a YouTube livestream the following day.
