Later in the conversation, he allegedly reiterated that he was looking for a chance to grab the rifle: “There is a squad car parked right by it. I think they already swept that spot, but I don’t wanna chance it.”

Eventually, he allegedly wrote that, “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 (sic) rifle.”

Robinson eventually surrendered to authorities in his hometown in southern Utah 33 hours after the slaying, after his parents and a family friend convinced him to turn himself in rather than take his own life, according to authorities.  

He faces charges including aggravated murder.
