FBI Director Kash Patel said Sunday that the FBI would address all of the public’s lingering questions about the recent assassination of conservative activist Charlie Kirk when “appropriate.”

In an update, Patel said that the investigation into Kirk’s killing was ongoing and that his agency was still exploring multiple theories about the killing. He said that the FBI would “ensure every question is addressed at the appropriate moment.”

“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,” he posted on X. “The full weight of America’s law enforcement agencies are actively following the evidence that has emerged, but our efforts extend beyond initial findings. We are examining every facet of this assassination.”

Patel said his agency was investigating several key questions, including the location of the shooting, whether suspected assassin Tyler Robinson had accomplices, the authenticity of an apparent text-message confession, activity in Discord chats, how the murder weapon was transported, “hand gestures observed as potential ‘signals’ near Charlie at the time of his assassination,” and visitors to Robinson’s home in the days leading up to the attack.

He added that some details are already known but can’t be shared while Robinson’s case is still under investigation and prosecution.

Patel addressed online claims that an airplane near the assassination site turned off its transponder shortly after Kirk was shot dead.

“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,” Patel said. 

“The entire FBI mourns the loss of Charlie Kirk. We will not rest until justice is served, and our investigation into this assassination will continue until every question is answered,” he added. 

Patel, along with other top Trump administration officials, attended a memorial service for Kirk on Sunday in Arizona, where nearly 100,000 people gathered to honor his legacy.
