History Channel personality, YouTube star, and extraterrestrial researcher David Wilcock has died at age 53 after an incident involving police response in Boulder County, Colo.

Local authorities reported that they responded Monday to an incident near the 1400 block of Ridge Road, where an emergency communications specialist dispatched officers over speculation that an individual was having a "mental health crisis."

Deputies arrived at approximately 11:02 a.m. local time, the report said, with police making contact with a man outside a residence who was "holding a weapon." He later "used the weapon on himself," the report continued, and was pronounced dead at the scene.

Police shared a photo from the scene of David Wilcock's death.
