The man suspected of killing conservative commentator Charlie Kirk texted his roommate after the shooting to discuss a possible motive, according to court documents.

Tribune Online reports that Tyler Robinson is now facing seven criminal charges, including aggravated murder, after the Utah County Attorney’s Office unveiled new details of the case on Tuesday.

County Attorney Jeffrey Gray told reporters that Robinson slipped the note under his computer keyboard for his roommate to find.

The unnamed roommate told investigators that Charlie Kirk’s suspect had alerted him to a confession under his keyboard after last Wednesday’s shooting at Utah Valley University campus in the city of Orem, said prosecutors.

Here’s the full record of a series of text messages between Charlie Kirk’s suspect and his roommate provided to investigators.

Robinson: drop what you are doing, look under my keyboard.

[When the roommate looked under the keyboard, there was a note that allegedly read: “I had the opportunity to take out Charlie Kirk and I’m going to take it.”]

Roommate: “What?????????????? You’re joking, right????

Robinson: I am still ok my love, but am stuck in orem for a little while longer yet. Shouldn’t be long until I can come home, but I gotta grab my rifle still. To be honest I had hoped to keep this secret till I died of old age. I am sorry to involve you.

Roommate: you weren’t the one who did it right????

Robinson: I am, I’m sorry

Roommate: I thought they caught the person?

Robinson: no, they grabbed some crazy old dude, then interrogated someone in similar clothing. I had planned to grab my rifle from my drop point shortly after, but most of that side of town got locked down. Its quiet, almost enough to get out, but theres one vehicle lingering.

Roommate: Why?

Robinson: Why did I do it?

Roommate: Yeah

Robinson: I had enough of his hatred. Some hate can’t be negotiated out.

Robinson: If I am able to grab my rifle unseen, I will have left no evidence. Going to attempt to retrieve it again, hopefully they have moved on. I haven’t seen anything about them finding it.

Roommate: How long have you been planning this?

Robinson: a bit over a week I believe. I can get close to it but there is a squad car parked right by it. I think they already swept that spot, but I don’t wanna chance it

Robinson: I’m wishing I had circled back and grabbed it as soon as I got to my vehicle…. I’m worried what my old man would do if I didn’t bring back grandpas rifle … idek if it had a serial number, but it wouldn’t trace to me. I worry about prints I had to leave it in a bush where I changed outfits. didn’t have the ability or time to bring it with…. I might have to abandon it and hope they don’t find prints. how the [expletive] will I explain losing it to my old man….

only thing I left was the rifle wrapped in a towel….

remember how I was engraving bullets? The [expletive] messages are mostly a big meme, if I see “notices bulge uwu” on fox new I might have a stroke alright im gonna have to leave it, that really [expletive] sucks…. judging from today I’d say grandpas gun does just fine idk. I think that was a $2k scope;-;

Robinson: don’t talk to the media please. don’t take any interviews or make any comments. … if any police ask you questions ask for a lawyer and stay silent
