(EPOCH TIMES) DNA evidence matching that of Charlie Kirk’s suspected killer was found at the crime scene, FBI Director Kash Patel said on Monday.

Tyler Robinson, the suspect arrested for the Sept. 10 assassination of the conservative Christian influencer at Utah Valley University, also left a note indicating that he expressed that he had an opportunity to kill Kirk, Patel said.

Patel said that it was both a “note” and a “text message exchange,“ adding that it was ”destroyed“ but that investigators recovered it. Other evidence in the case, Patel said, was ”shocking,” although he didn’t go into more detail.

Touching on a possible ideologically based motive, Patel said that Robinson’s family said that he “subscribed to left-wing ideology,” echoing a statement made by Utah Gov. Spencer Cox during several Sunday interviews about the suspect’s viewpoints.

“Friends have confirmed that there was kind of that deep, dark internet, the Reddit culture, and these other dark places of the internet where this person was going deep,” the governor said.

And he added that his “roommate was a romantic partner, a male transitioning to female.”

“I can say that he has been incredibly cooperative, this partner has been very cooperative, had no idea that this was happening,” Cox said.

This past week, Cox also said that the suspected killer engraved messages containing anti-fascist viewpoints on bullets that were recovered by authorities. Court records and Cox said that one bullet casing had the message, “Hey, fascist! Catch!”

Kirk founded Turning Point USA in 2012 to bring more young, conservative evangelical Christians into politics as effective influencers, and he was a confidant of President Donald Trump. Nationwide, vigils were held, including one Sunday night at the Kennedy Center in Washington.

Kirk, a 31-year-old father of two, became prominent in part through his campus speaking tours. He was shot on Wednesday while answering a question at the college in Orem, Utah.

Speakers at the Kennedy Center included White House press secretary Karoline Leavitt, Director of National Intelligence Tulsi Gabbard, two House members whose remembrances of Kirk were briefly stalled when they teared up, Health Secretary Robert F. Kennedy Jr., House Speaker Mike Johnson, and White House adviser Stephen Miller.

“I had a conversation once with Charlie. We were talking about the danger that we were both challenging entrenched interests, and he asked if I was scared of dying. And I said, ‘There’s a lot worse things than dying,’” Kennedy said.

With Kirk’s death, Kennedy said that “it’s our job” to “win this battle for our country.”
