Demi Helenius: Missing Oregon Woman’s Car Found After Landmark Worldwide Seminar Disappearance


Demi Helenius, also known as Demi Helenius-Culley, is an Oregon woman who vanished without a trace over the weekend. Now, police say her car has been found. The Washington County Sheriff’s office stated they need help finding the 23-year-old missing woman. Demi Helenius disappeared on the night of Saturday, August 5, after attending a Landmark Worldwide self-help conference at the Embassy Suites hotel in Portland, Oregon. Update: Demi Helenius was found safe in Roseburg.


According to police, Demi Helenius-Culley was last seen at the Landmark Worldwide conference, which ended at about 10 p.m. Landmark Worldwide Forum attendees say Demi went to lunch at 6:00 p.m. and never returned for the last half of the conference. Worried family members say Demi Helenius also failed to return home. All calls to her phone have gone unanswered. Losing communication with her family is unusual for Demi Helenius. She normally talks to someone by text or by phone, Oregon Live reported.


Authorities say something even more disturbing happened on the night of her disappearance. A male stranger pulled up to the Creswell Dairy Queen drive-thru window and told an employee he found a phone. He later told Oregon investigators he turned the phone in after he saw someone throw it from a vehicle. Authorities say the phone belongs to Demi Helenius.


Detectives say that same night, there was another person who didn’t return from the 6:00 p.m. dinner break at the Landmark Worldwide conference. They are digging into his background but say they don’t have any suspects, according to a report by KGW-8.
