BUSHONG, J. This criminal case requires us to decide two issues relating to defendant’s convictions on two counts of felony murder. The first issue is whether the trial court erred in declining to suppress statements that defendant made during a police interrogation after he was arrested for setting fire to his estranged girlfriend’s apartment, killing her two roommates. The second issue is whether Oregon’s felony -murder statute, ORS 163.115(1)(b), as applied to defendant violates the Due Process Clause of the Fourteenth Amendment to the United States Constitution. The Court of Appeals concluded that defendant’s statements were voluntary and thus admissible, and that the felony-murder statute did not violate defendant’s right to due process. State v. Monaco, 336 Or App 684, 561 P3d 650 (2024). We allowed review and now affirm on both issues.

As we will explain, our case law regarding the first issue establishes that the ultimate question for the court is, in the totality of the circumstances, whether defendant confessed voluntarily, or his free will was overborne by improper threats or inducements by the police. State v. Jackson, 364 Or 1, 430 P3d 1067 (2018). We agree with the Court of Appeals that the trial court did not err in concluding that the state met its burden of establishing that defendant’s free will was not overborne; rather, he confessed voluntarily. On the second issue, we conclude that the felony-murder statute , ORS 163.115(1)(b), as interpreted in State v. Blair, 348 Or 72, 228 P3d 564 (2010), did not violate defendant’s constitutional right to due process.

I. FACTS AND PROCEEDINGS BELOW The facts that are relevant to our review are those related to the trial court’s denial of defendant’s motion to suppress. We review a trial court’s ruling on a motion to suppress for errors of law. State v. Ehly, 317 Or 66, 75, 854 P2d 421 (1993). Whether a confession was voluntary is a question of law. Jackson, 364 Or at 21. In reviewing that question for legal error, we are bound by the trial court’s factual findings if there is constitutionally adequate evidence to support them, and we “presume that the facts were decided 4 State v. Monaco

in a manner consistent with the court’s ultimate conclusion” if the trial court did not make express findings. Ehly, 317 Or at 75. We summarize the facts from the trial court record in accordance with that standard. A. Historical Facts Defendant began dating TM in 2013, and they lived together in an apartment at various times from 2013 to 2017. Their relationship was volatile. In April 2017, TM sought and obtained a restraining order, alleging that defendant had assaulted her. Nevertheless, TM continued to see defendant and she frequently invited him to the apartment despite the restraining order. TM lived in the apartment with two roommates, J and T.

On July 22, 2017, defendant and TM went to a bar together and they got into an argument. Defendant eventually drove TM home, and he entered her apartment to use the bathroom. Fearing that their encounter was going to “get ugly,” TM left while defendant was in the bathroom and returned later that night to see whether defendant was still at the apartment. As she drove into the parking lot, defendant rear-ended her car with his car. TM drove away, but defendant followed and struck her car multiple times as they drove on the freeway. TM eventually slammed on her brakes, and defendant kept driving. TM called 9-1-1 to report the incident and drove to her sister’s house.

Defendant returned to TM’s apartment and repeatedly called and texted TM, begging her to return to the apartment. During one of those calls, he told TM that he was going to drench her couch in gasoline and light it on fire. He told TM that he would videocall her so that she could watch him pour the gasoline. A short while later, defendant called TM and told her that he was “really sorry,” that he had “really fucked up,” and that he was going to take his own life. A couple of minutes later, TM received a text message from her other sister stating that TM’s apartment was on fire. Surveillance footage from a neighboring property captured video images of defendant leaving TM’s apartment as the fire erupted.

The fire spread quickly. TM’s roommates, J and T, had been asleep in an upstairs bedroom at the time; they died in the fire, along with a dog and three snakes. An arson investigator determined that the fire had started in the living room after someone had poured accelerant on the couch. The police arrested defendant following a brief pursuit three days after the fire. After the arrest, defendant was taken to the hospital for medical treatment. He was released from the hospital around 1:00 a.m. and taken to jail, where he spent the night. B. The Interrogation Around noon the following day, Detectives Michaels and Luiz took defendant to an interrogation room at the jail. Michaels advised defendant of his Miranda rights, and defendant stated that he understood his rights and agreed to speak with her. The interrogation lasted about four hours.

Michaels began by asking defendant biographical questions before inquiring about his relationship with TM and the reason that she had obtained a restraining order that excluded him from the apartment that they had previously shared. Defendant acknowledged that he had a volatile relationship with TM but denied that he had ever hit her. Defendant stated that, despite the restraining order, TM had invited him to the apartment nearly every day.

Michaels then asked defendant about the events of the day and night leading up to the fire. Defendant said that he and TM had gone to a bar, they had an argument, and he had driven her home around 1:30 a.m. Defendant claimed that he left the apartment at about 2:00 a.m. and spent the rest of the night hanging out with his cousin Larry. Defendant stated that he had learned about the fire when a neighbor called him between 4 and 5 a.m. He suggested that TM or one of her roommates could have started the fire.

Michaels then suggested that they take a break and offered to get defendant water or anything else he needed. When she returned to the interview room, Micheals told defendant that she had looked at TM’s phone and could tell from his calls and text messages that he had remained in the apartment until about 3:20 a.m., and that a neighbor’s 6 State v. Monaco

security camera had shown him leaving the apartment when the fire started. Michaels then asked defendant to tell her what “really happened,” stating that she knew that defendant had threatened to soak TM’s couch in gasoline. Defendant responded by stating that he did not remember starting the fire.

Michaels then told defendant that it would “ease”
