Billings, Montana - March 14, 2026 - The disappearance of Dr. Sean McMillan, a prominent figure in the study of Unidentified Aerial Phenomena (UAP) - commonly known as UFOs - has deepened into a major search operation, with Montana law enforcement now urgently requesting assistance from the public. Dr. McMillan, 55, has been missing since March 6th, last seen at his residence in the Lockwood area of Billings. The Billings Police Department issued a press release today, March 14th, broadening the scope of the investigation and appealing for home security footage that might offer clues to his whereabouts.

The call for video footage represents a significant escalation in the case, suggesting investigators haven't yet uncovered concrete leads. Authorities are asking residents within a wide radius of Dr. McMillan's home to review recordings from security cameras, doorbell cameras, and any other video surveillance systems they may operate, focusing on the period between March 6th and the present day. They are particularly interested in any unusual activity, vehicles, or individuals observed in the Lockwood area.

"We are exploring all avenues of investigation," stated Sergeant David Miller of the Billings Police Department. "Dr. McMillan's expertise and public profile raise the possibility that his disappearance could be linked to his professional work, but we're keeping an open mind and pursuing all credible leads. Public assistance, particularly in the form of potentially relevant video footage, is crucial at this stage."

Dr. McMillan is a highly respected researcher and analyst within the UAP community. He has spent over two decades studying unexplained aerial sightings, appearing as an expert commentator in numerous documentaries and media outlets. His meticulous approach to data analysis and his ability to separate credible reports from unsubstantiated claims have earned him a dedicated following among both UAP enthusiasts and skeptics alike. He wasn't a sensationalist, often advocating for rigorous scientific investigation rather than jumping to extraterrestrial conclusions.

His wife, Susan McMillan, spoke to reporters earlier this week, expressing her profound worry and describing her husband's disappearance as completely out of character. "Sean is a creature of habit," she said. "He always lets me know where he's going, and he's in constant communication. The fact that we haven't heard from him in over a week is terrifying. We just want him home safe."

The timing of Dr. McMillan's disappearance has fueled speculation within the UAP community, particularly given the increased governmental and public interest in UAP in recent years. The release of the 2023 and 2024 reports from the All-domain Anomaly Resolution Office (AARO) - a US Department of Defense entity tasked with investigating UAP - have brought the topic into the mainstream, and Dr. McMillan was a frequent contributor to discussions surrounding these findings. Some online forums are already buzzing with theories linking his disappearance to sensitive information he may have possessed or research he was conducting. However, law enforcement officials are urging the public to avoid spreading unverified information and to allow them to conduct a thorough investigation.

The search is currently being conducted by the Billings Police Department, with assistance from the Yellowstone County Sheriff's Office and Montana Search and Rescue teams. Teams are combing the area surrounding Dr. McMillan's home, utilizing ground searches, aerial surveillance, and K-9 units. Digital forensics experts are also analyzing Dr. McMillan's computer and electronic devices for any clues.

The Billings Police Department is urging anyone with information, no matter how insignificant it may seem, to contact them immediately. The dedicated tip line is (555) 123-4567. The department is also encouraging residents to submit any relevant video footage through a secure online portal on the city's website. This is an ongoing investigation, and updates will be provided as they become available.
