Before leaving his apartment for the final time, the suspect in Charlie Kirk’s killing allegedly wrote a chilling note explaining why he targeted the conservative activist and icon.

FBI Director Kash Patel said that investigators are getting forensic proof about the note that has since been destroyed. Robinson, 22, informed his roommate and transgender lover that he had a single opportunity to “take out” Kirk before he fled permanently.

“The written note did exist, and we have evidence to show what was in that note,” Patel said on Fox News.

“‘I have the opportunity to take out Charlie Kirk and I’m going to take it,’” he claimed the note stated. “That note was written before the shooting.”

Patel claimed that the FBI has found forensic evidence that proves what was written on the message, even though it was destroyed in the partner’s home.

Patel also credited “aggressive” interview tactics employed with Robinson, who authorities say is not cooperating with the investigation. He is currently being held under “special watch” in Utah.

It’s unclear if the note was left for Robinson’s roommate, who relatives say “hated conservatives and Christians” but has been turning over evidence implicating Robinson in the assassination.

Patel also didn’t say if the memo was digital or physical or how it was found.

Robinson is not facing charges in connection with Kirk’s death, but he was in the process of changing from male to female when he reportedly shot and killed Kirk. Spencer Cox, the governor, said on Sunday that the inquiry has shown that Robinson had a “leftist ideology” that may have been strengthened by his friendship with his roommate.

A female relative of the roommate, who wanted to stay unidentified, told Fox News that he had become quite misanthropic toward Christians and conservatives since he turned 18.

“He hates conservatives and Christians,” the relative said. “He hated us. He was not raised that way, but he, over the years, has become really detached [and] been radicalized.”

“He has obviously gotten progressively worse the last year or two,” the relative said, adding that he’s “always very angry.”

Patel also said that detectives have found DNA evidence that ties Robinson to the scene of the shooting.

This comes after police made another arrest in the Kirk case this week.

A known political activist who falsely claimed that he shot Charlie Kirk while at the event for the conservative star told police that he was doing it to “draw attention away from the real shooter.”

According to Fox 13 in Utah, 71-year-old George Zinn, who was a known “gadfly” and was led away from Utah Valley University in handcuffs after the murder last Wednesday, told police he was trying to distract them from the real killer.

According to the report, Zinn went up to the police right after Kirk was killed and yelled, “I shot him, now shoot me.” Police said he wasn’t carrying a gun and arrested him.

During a police interview, Zinn admitted he did not kill Kirk but said he wanted to cause a distraction “to draw attention from the real shooter,” according to court documents reviewed by Fox 13.

According to court papers, the fake shooter said he “wanted to be a martyr for the person who was shot” after being taken to a local hospital for medical reasons.

Police said that his first words slowed down the investigation into Kirk’s death and wasted police time and energy at a crucial point in the case.

He is charged with obstruction of justice, which is a second-degree felony.

There was a lot of chaos at Utah Valley University after the murder, and video from that time showed Zinn being dragged away by police while he screamed, “Shoot me!”

“He said he shot him, but I don’t know,” one officer told the crowd, which was under the impression that Zinn was the shooter and yelled and swore at him as he went by.
