FBI Director Kash Patel vowed on Sunday to investigate every facet of Charlie Kirk's killing, and made a statement about a mystery airplane flight at the heart of numerous Charlie Kirk shooter conspiracy theories.

Patel over the weekend took to X to make a promise about the state of the investigation into the Kirk killing. Kirk was killed by a long-range shooter in Utah during a "prove me wrong" event at a college.

"As the Director of the FBI, I am committed to ensuring the investigation into Charlie Kirk’s assassination is thorough and exhaustive, pursuing every lead to its conclusion. The full weight of America’s law enforcement agencies are actively following the evidence that has emerged, but our efforts extend beyond initial findings," he wrote. "We are examining every facet of this assassination. We are meticulously investigating theories and questions, including the location from where the shot was taken, the possibility of accomplices, the text message confession and related conversations, Discord chats, the angle of the shot and bullet impact, how the weapon was transported, hand gestures observed as potential 'signals' near Charlie at the time of his assassination, and visitors to the alleged shooter’s residence in the hours and days leading up to September 10, 2025."

Patel added, "Some details are known today, while others are still being pursued to ensure every possibility is considered. Our primary focus is to complete this investigation and deliver justice. To protect the integrity of the investigation and subsequent prosecution, we cannot release every piece of information we have to the public right now. We will ensure every question is addressed at the appropriate moment."

He went on to address the flight that some say the killer took after the shot.

"Regarding specific details, such as questions about the plane that allegedly turned off its transponder after departing from an airport near the assassination site, we can share updates when answers are confirmed. After interviews with the pilot and consultation with the FAA, we determined the transponder was not turned off. Incomplete flight data in rural areas caused the apparent gap. The entire FBI mourns the loss of Charlie Kirk," Patel wrote. "We will not rest until justice is served, and our investigation into this assassination will continue until every question is answered."
