The State

On Appeal from the Superior Court of DeKalb County No. 19CR18528

Decided: August 13, 2026

MCMILLIAN, Justice. Jonathan Mansfield appeals from his convictions for malice murder and other crimes in connection with the death of Lee Castillo . 1 On appeal, Mansfield argues that (1) the trial court erred in admitting Mansfield’s custodial statement in violation of his rights under Miranda 2 and OCGA § 24-8-824; (2) the admission

1 The crimes were committed on February 1, 2019. In April 2019, a DeKalb County grand jury indicted Mansfield for malice murder (Count 1), three counts of felony murder (Counts 2-4), two counts of aggravated assault (Counts 5 and 6), and burglary in the first degree (Count 7). At a jury trial in February 2024, Mansfield was found guilty of all counts except Count 4. On March 7, 2024, the trial court sentenced Mansfield to serve life in prison without the possibility of parole for malice murder (Count 1) and a consecutive term of twenty years in prison for burglary in the first degree (Count 7). The other counts were either vacated by operation of law or merged for sentencing purposes . Mansfield timely filed a motion for new trial, which was amended through new counsel on October 19, 2025. Following a hearing, the trial court denied the motion for new trial, as amended, on December 10, 2025. Mansfield timely filed a notice of appeal, and his case was docketed to this Court’s April 2026 term and submitted for a decision on the briefs.

2 See Miranda v. Arizona, 384 US 436 (1966).

of extensive crime-scene and autopsy photographs and other physical evidence created unfair prejudice such that a new trial is required; (3) the voluntary manslaughter instruction was confusing ; and (4) the cumulative effect of the errors requires reversal . For the reasons that follow, we affirm.

The record shows that at 6:28 p.m. on February 1, 2019, Castillo called 911 to report that someone he knew was breaking into his house, although Castillo did not identify the person. Michael Hudson, one of Castillo’s neighbors, testified that the same night, he heard “screaming for a while,” including hearing “please, no, stop.” After walking in front of Castillo’s house, Hudson saw a silhouette of “somebody, like, raising – all I could see was somebody raising their arm, essentially, and bringing it down.” He stated that when he called out to ask if everything was okay, there was no response but “you could tell that he turned and then looked … he definitely looked like he had been caught doing something.” When responding officers arrived at the scene, they found a large amount of blood around the carport of the house and Castillo, who was deceased. The crime technician noted that there was a strong odor of gas in the house and saw a gas can next to the carport door, as well as some burn and charred patterns on the hardwood floor. Inside the house on a table was a brick stained with blood. Also, Castillo’s 2017 Toyota Corolla was missing .

The next morning, a patrol officer found Castillo’s car in Chattanooga. DNA tested from blood on the steering wheel and from cigarette butts found in the car both matched Mansfield’s DNA. At trial, FBI special agent James Berni testified to using Mansfield’s cell phone records and mapping based on those records to identify the approximate location of Mansfield at different times during these events. Agent Berni testified that Mansfield’s

phone was in the general area of the murder during the time of the murder based on his phone using the closest phone tower to the crime scene at 7:27 p.m. Also, Mansfield’s phone was located in Chattanooga, using phone towers near where Castillo’s car was eventually found at 11:20 p.m. the night of the incident.

Castillo’s partner Will Smith testified that he lived with Castillo and that they considered themselves to be married. Smith testified that he and Castillo met Mansfield through video games, and that after a few months, Mansfield began visiting them and would visit once a month for a few days at a time. About a week before the incident, they discovered that Mansfield tried to use their credit card without their approval. They tried to call Mansfield about the card use multiple times but never heard back from him. Mansfield was no longer welcome in their home at that point. After leaving for work the afternoon of February 1, Smith came back to the house around midnight to find police at their house and on their street. When he finally was able to get into the house, he discovered that several video game consoles were missing , as well as an Apple watch. The next morning, while cleaning the back porch, Smith found a gold necklace outside on the back patio near where Castillo’s body was found, which Smith believed belonged to Mansfield.

Mansfield testified in his own defense that he met Castillo through online gaming around October of 2017. A few months later, he began meeting Castillo and Smith in person, ultimately about 12 times in total. Mansfield claimed that he went to Castillo ’s house on February 1 to retrieve some of his personal belongings that he had left there. After arriving around 5:00 p.m., he waited in the garage until Castillo arrived. When Mansfield approached Castillo, Mansfield claimed that Castillo was “immediately like verbally violent” and cursing at him. As Mansfield went

to get his items from the house by going around Castillo, Castillo pulled a gun from his hip. Mansfield reached for the gun, and they “got into a wrestling match slash fight over the gun.” After the gun “went flying,” Castillo grabbed a brick and hit Mansfield with it. Mansfield then grabbed his knife out of his pocket and began stabbing Castillo because he was “scared that this guy was going to kill me if I didn’t do something.” Mansfield and Castillo continued fighting over the knife until Mansfield grabbed a brick and hit Castillo in the head, ending the fight. Mansfield testified that he then tried to call 911, but the call did not go through. He went to collect his things in the house, called his friend, grabbed Castillo ’s car keys, and since he was “freaking out,” grabbed a nearby gas can and started pouring gas around the home and on clothes that he had taken off Castillo and lit the gas on fire before leaving. He then drove to Chattanooga in Castillo’s car, abandoned the vehicle , and had a friend pick him up.

Soon after, Mansfield was arrested and on February 5, Investigator Michele Johnson took pictures of Mansfield. Investigator Johnson testified that while Mansfield had several cuts and scratches on his hands, there were no other injuries noted or documented . The medical examiner who conducted Castillo’s autopsy stated that there were multiple blunt force trauma injuries to Castillo’s face and head, along with some sharp object injuries. He concluded that the cause of death was “the sharp blunt force injuries of the head, neck, torso, and extremities” and that the manner of death was homicide.

1. Mansfield first argues that the trial court erred in admitting his custodial statement under Miranda and OCGA § 24- 8-824 after he referenced counsel and asked to wait for his lawyer. This claim fails.
