Probable Cause Affidavit — Tyler Robinson

This is the Probable Cause Affidavit filed by law enforcement in connection with Tyler Robinson's arrest. This is the police-side booking document that established the legal basis for Robinson's detention.

The affidavit contains the official law enforcement account of the timeline of events, including references to the "early morning hours of September 12, 2025." Investigators have noted that this language refers to a distinct, later encounter by Utah County investigators — not the initial Miranda encounter documented in Bates 003996-R2, which occurred at approximately 6:25 PM MDT on September 11, 2025.

Tyler Robinson is charged, not convicted. All references to his alleged conduct are allegations drawn from official court documents. Nothing in this document constitutes a finding of guilt.

Key Points​

  • The affidavit is the law enforcement counterpart to the defense's Miranda timeline argument.
  • Its reference to "September 12, 2025 early morning hours" describes Utah County investigators arriving after a multi-hour drive from Provo — not the initial Miranda reading at 6:25 PM.
  • The document was filed as part of the formal arrest record and establishes the legal basis for Robinson's continued detention without bail.
  • Readers should consult the original filing and defense responses for the full legal context.
