Santaquin, Utah – A Provo courtroom became the center of a heated legal battle as attorneys for truck driver Michael Aaron Jayne claimed the fatal strike on Sgt. Bill Hooser resulted from an unavoidable maneuver, not deliberate murder.[1][2] The preliminary hearing, spanning multiple sessions, featured dash camera footage and expert testimony that painted a picture of chaos on Interstate 15.[3] Nearly two years after the incident, prosecutors remain committed to proving intent in pursuit of the death penalty, leaving the outcome hanging until June.[2]
Chaos Erupts from Routine Traffic Stop
On May 5, 2024, Sgt. Bill Hooser, a veteran Santaquin Police officer, joined Utah Highway Patrol Trooper Dustin Griffiths for a traffic stop on I-15.[2] Reports had surfaced of a person standing on the back of Jayne’s semitruck, prompting the intervention.[3]
Inside the cab sat Christine Hinckley, who later testified that Jayne held her against her will during a multi-state journey marked by methamphetamine use and paranoia.[1] She warned Hooser that Jayne posed a danger before he fled, executing a U-turn against oncoming traffic.[2] The semitruck, moving at about 15 mph, smashed into patrol cars and struck Hooser, who died at the scene.[2]
Jayne attempted to escape by stealing a smaller truck but was quickly apprehended.[1] Crash reconstruction expert Charles Funk later detailed a 16.5-second timeline from the U-turn initiation to impact, noting the truck’s blind spots and handling differences from standard vehicles.[2]
Key Testimony Emerges in Provo Court
The preliminary hearing began in January 2026, with prosecutors calling Griffiths and Hinckley.[2] The second session on March 26 featured defense witnesses, including Funk and truck driver Derik Christensen.[1]
Christensen described coming head-to-head with Jayne’s semitruck on an on-ramp, swerving to safety while watching the collision unfold in his mirrors.[2] The court viewed dash camera footage capturing the sequence.[3] Funk testified that Jayne swerved left in a “reasonable response” to avoid Christensen’s vehicle, rendering the path toward police cars inescapable.[2]
Jayne, during a post-arrest interview, reportedly broke down crying upon learning an officer had died, claiming he never saw Hooser.[2]
Defense Pushes Back on Murder Allegation
Rudy Bautista, Jayne’s attorney, asserted after the hearing, “As we’ve been trying to explain to the state of Utah from day one, this was never and is not an intentional murder.”[2] He described the event as stemming from “poor choices” but argued for reckless automobile homicide over aggravated murder.[1]
Bautista highlighted Jayne’s remorse, noting, “At trial, I’m presuming those videos will be played, and you’ll see Michael Jayne breaking down and crying when he found out what had happened.”[1] He suggested a life sentence could bring faster closure for Hooser’s family than prolonged death penalty proceedings.[2]
- Capital aggravated murder
- Two counts of attempted aggravated murder
- Aggravated kidnapping
- Three counts of theft of a vehicle
- Two counts of failure to stop at the command of police
- Property damage
- Attempted theft of a firearm or vehicle
- Reckless endangerment
- Possession or use of a controlled substance
- Driving under the influence
These represent the 15 charges Jayne faces.[3][2]
Incarceration Marked by Further Violence
While awaiting trial at Utah County Jail, Jayne faced additional accusations.[4] In July 2025, he assaulted three deputies during a contraband interview, injuring them and earning charges of aggravated assault by a prisoner and criminal mischief.[5]
November brought more charges, including assault by prisoner and an incident involving sprayed liquid.[6] These events compounded his legal troubles but did not alter the core murder case.[7]
Toward a Pivotal June Decision
Deputy Utah County Attorney Chad Grunander responded to the defense by affirming, “We have charged this as aggravated murder, which requires us to prove beyond a reasonable doubt that the defendant acted intentionally or knowingly, and we look forward to making our case in court.”[1] Both sides will submit briefs before oral arguments on June 18, when the judge decides on binding Jayne over for trial.[2]
Key Takeaways
- Defense evidence points to an unavoidable swerve amid blind spots and split-second decisions, rejecting intent.
- Prosecutors hold firm on aggravated murder, eyeing the death penalty phase if convicted.
- A June 18 hearing will determine if the case advances to full trial after nearly two years.
The Hooser family’s long wait for resolution underscores the gravity of the loss felt across Utah’s law enforcement community. As briefs are prepared, the collision’s circumstances remain fiercely contested. What do you think about the defense’s unavoidability argument? Tell us in the comments.
