Story summary

Defense attorneys filed a 41-page brief Tuesday asking the court to strike the sole aggravating factor in Tyler Robinson’s case.
They argue the bullet only struck Charlie Kirk and did not endanger the crowd at Utah Valley University on Sept. 10, 2025.
Prosecutors say the rooftop shot created a great risk of death to others and point to a text to roommate Lance Twiggs as evidence of a political motive.

History

Historical Context

The Supreme Court’s 2005 decision in United States v. Booker struck the mandatory status of the Federal Sentencing Guidelines, turning them advisory after earlier rulings such as Blakely v. Washington (2004). By invoking the Sixth Amendment, the Court required judges to consider the Guidelines only as one factor and to review sentences for “reasonableness.” The change doubled the rate of sentences that exceed guideline ranges, prompting judges and scholars—including Utah Valley University lawyers—to question the use of single-bullet aggravating factors today.
