Investigators say they interviewed the roommate of the suspect in the fatal shooting of Charlie Kirk and that the roommate — identified as Lance Twiggs — provided law enforcement with electronic messages sent from the suspect’s account.

Authorities say the roommate and other witnesses have cooperated with investigators throughout the inquiry.

According to screenshots and accounts provided to investigators, an account linked to Tyler Robinson sent a series of messages to his roommate that culminated in an apparent admission.

In one message posted the evening before Robinson surrendered, the account stated: “Hey guys, I have bad news for you all. It was me at UVU yesterday. I’m sorry for all of this.” Investigators are treating the messages, the accompanying screenshots and the roommate’s cooperation as part of their evidentiary review.

Officials also provided investigators with prior, more detailed exchanges between Robinson and the roommate that allegedly occurred around the time of the shooting.

Those messages, as described by law-enforcement sources, include the following elements:

A text directing the roommate to “look under my keyboard,” where the roommate found a handwritten note stating: “I had the opportunity to take out Charlie Kirk and I’m going to take it.” Police say they recovered a photograph of the note.

Subsequent text exchanges in which the roommate expressed shock and disbelief, and Robinson’s account acknowledged responsibility, writing, “I am, I’m sorry.”

Additional messages attributed to the suspect that discussed logistics about a rifle, a prearranged “drop point,” concern about law-enforcement presence in the area, and plans to retrieve or abandon a firearm left in vegetation.

Those messages reportedly referenced leaving the rifle wrapped in a towel and concerns about fingerprints and serial numbers. At one point Robinson’s account reportedly wrote that he had been engraving bullets and made crude references to online commentary about the incident.

Later in the exchange the account stated an intention to surrender: “I’m surrendering through a sheriff friend in a few moments,” and urged the roommate not to speak to the media and to request a lawyer if questioned by police.

Law-enforcement sources say the roommate provided the messages to investigators and has been cooperating with questioning. Officials have not publicly disclosed whether the messages have been authenticated as originating from Robinson’s device or account; forensic analysis of electronic evidence is ongoing.

Investigators also interviewed family members. According to law-enforcement summaries, Robinson’s mother told investigators that over the past year her son had become more politically engaged and had formed a romantic relationship with his roommate, who is a biological male undergoing a gender transition. Family members said this relationship led to tensions within the household, particularly between Robinson and his father, who hold differing political views.

Robinson’s father told investigators he recognized his son in surveillance images broadcast by news outlets and believed the rifle recovered near the scene resembled a firearm previously given to his son. He said he attempted to contact Robinson and later spoke by phone with him; during that conversation Robinson reportedly implied he was contemplating suicide and acknowledged involvement in the shooting. Family members arranged for a retired deputy sheriff, a trusted family friend, to meet with Robinson; that intervention resulted in Robinson surrendering to authorities, according to investigators.

Police and prosecutors are treating the electronic communications, the roommate’s statements, family interviews and physical evidence collected at and near the scene as components of an active homicide investigation. Authorities have said they will rely on forensic analysis — including authentication of digital messages, ballistics, and other laboratory testing — before drawing final conclusions about motive, planning, or the exact sequence of events.

Because the matter remains under active investigation and potential prosecution, officials have not released the full body of evidence or answered all questions about the chronology and provenance of the messages. Investigators have asked anyone with relevant information to come forward.
