A mother’s three-word plea to a Texas jury came only after a verdict she had spent over a year dreading, and the words she chose said everything about what was at stake for her family.
Kayla Hayes stood before jurors on June 9, 2026, not as a bystander but as the very first witness called during the sentencing phase of her son’s murder trial.
Her time on the stand came just minutes after Karmelo Anthony, 19, was found guilty of killing 17-year-old Austin Metcalf — a verdict that triggered a wave of raw emotion inside the Collin County Courthouse that neither family will ever forget.
The conviction closed a chapter that started at a high school track meet more than a year prior and had since consumed two families, an entire community, and a nationwide debate about race, self-defense, and personal accountability.
During the sentencing phase, both sides chose to skip opening remarks, and the prosecution quickly rested. The defense then called Kayla to take the stand.
Testifying in front of the jury, she explained that Karmelo is her firstborn — ‘He’ll always be my baby. I love him very much,’ — and told jurors her son was deeply remorseful for what he had done. ‘I know my son, and he’s very sorry for what he did,’ she said.
When defense attorney Mike Howard asked whether she had any final message for the jury, Hayes answered without hesitation: ‘Please have mercy on my son.’ Her plea landed in a courtroom still shaken by the guilty verdict that had come just moments before.
The jury’s decision followed days of testimony about a confrontation that witnesses described as entirely of Karmelo’s making. Several students from Memorial High School took the stand and said Karmelo walked into their team’s tent to get out of the rain and refused repeated requests to leave.
As the situation escalated, Karmelo taunted Austin Metcalf, warning him, ‘Touch me and see what happens.’ Witnesses testified that he kept one hand inside his backpack and implied he had something concealed inside.
When Austin eventually shoved Karmelo’s shoulders, Karmelo stood up and stabbed him in the chest. Jurors rejected Karmelo’s self-defense claim and returned a guilty verdict on the murder charge.
The guilty verdict set the stage for an equally charged sentencing phase — one that included not only Kayla’s testimony, but a victim impact statement from Austin’s twin brother and a final jury deliberation that determined exactly how many years Karmelo would spend behind bars.
A Texas jury reached a major decision in the case against Karmelo Anthony for the death of Austin Metcalf. The ruling came after jurors rejected a self-defense claim and declined to find that the killing occurred under what Texas law calls ‘sudden passion.’
Was Karmelo Anthony acting in self-defense, or did prosecutors prove his use of force was not legally justified? That question sat at the heart of a trial at the Collin County Courthouse, where jurors ultimately convicted him of murder, turned down a request for a reduced sentence, and handed down a 35-year prison term.
Jurors spent fewer than three hours deliberating after hearing sharply conflicting accounts of the confrontation that unfolded during a high school track meet on April 2, 2025.
According to NBC DFW, Karmelo admitted to fatally stabbing Frisco student Austin Metcalf during the encounter. Both Karmelo and Austin were 17 years old at the time. Karmelo is now 19.
Before deliberations began, prosecutors and defense attorneys spent the trial’s final hours laying out competing versions of events and arguing over whether Karmelo’s actions were legally justified.
The final day of the trial got underway shortly after 9:15 a.m. on Tuesday, June 9, 2026, with a dispute over what the jury would be permitted to consider.
Judge John Roach addressed proposed jury instructions, including a legal principle known as ‘provoking the difficulty.’ That doctrine can limit a self-defense claim if jurors conclude the defendant deliberately provoked a confrontation.
Defense attorney Mike Howard objected to including that instruction, but Judge Roach denied the request and allowed it to stay in the jury charge.
The judge also declined to add criminally negligent homicide as a possible verdict. He did, however, approve manslaughter as a lesser included offense.
Shortly before 9:30 a.m., Judge Roach explained that jurors would choose between three possible outcomes: murder, manslaughter, or not guilty.
Karmelo had pleaded not guilty to murder, and the judge reminded jurors he was presumed innocent unless prosecutors proved the charge beyond a reasonable doubt.
Judge Roach also instructed jurors to weigh Karmelo’s self-defense claim and consider whether he had forfeited that defense by provoking the confrontation.
The distinction between possible verdicts was significant. A murder conviction carried a punishment range of five to 99 years, while manslaughter carried a possible sentence of two to 20 years.
At 9:56 a.m., Howard opened his closing argument by urging jurors to focus on what Karmelo believed in the moments leading up to the stabbing.
Howard argued that Austin had every right to ask Karmelo to leave the Memorial High School tent, but did not have the legal right to use physical force against him.
‘The government wants this case to be about, ‘Melo could have just left,” Howard told jurors. ‘Sure, he could have. I’m sure he wishes he did.’
From there, Howard framed the encounter as a fast-moving situation in which Karmelo believed he was cornered. He pointed to testimony that Karmelo remained seated while Austin and others stood over him inside the tent.
Howard also stressed testimony that Karmelo repeatedly warned those around him not to touch him.
‘If I look at you and repeatedly tell you, ‘Don’t touch me, I have something in my bag,’ that is the ultimate warning to back off,’ Howard argued.
Howard maintained that Karmelo believed he was defending himself during the confrontation. ‘There is no evidence Karmelo did anything but really think he was defending himself in that split second of chaos,’ Howard told jurors.
He also pointed to Karmelo’s behavior after the stabbing, including testimony that he appeared emotional and asked whether Austin would be okay.
At 10:18 a.m., prosecutor Bill Wirskye delivered the state’s response and urged jurors to reject the defense’s framing. ‘Do not let them turn a threat into a warning,’ Wirskye told jurors.
Wirskye argued that Karmelo brought a concealed knife to the track meet and used deadly force in a situation that did not justify it.
‘He took a knife to a track meet,’ Wirskye said. ‘He had a secret, he kept it hidden… He was the only one with a knife that day. He was always going to come out on top that day.’
According to FOX 4 News, Wirskye described the case as a ‘provoked, unjustified murder.’ He argued that Karmelo entered a closed team tent and carried out what he called a ‘sneak attack’ before running away.
Wirskye also challenged why Karmelo never chose to walk out of the tent before things spiraled. ‘You don’t get to meet a shove with a stab, especially if you provoke the shove,’ he argued.
The prosecutor told jurors the case was not about race and did not involve lawful self-defense. He argued the evidence supported the state’s version of events and concluded, ‘Ultimately, this case is about accountability,’ Wirskye said.
At 10:50 a.m., jurors left the courtroom to begin deliberating. Their job was to determine whether prosecutors had proven murder, whether the lesser offense of manslaughter applied, or whether Karmelo should walk free.
By early afternoon, the courtroom began filling up again as the parties prepared for the jury’s return.
At approximately 2:14 p.m., Karmelo and his attorneys came back into the courtroom.
According to NBC DFW, Karmelo’s mother appeared to have been crying while waiting in a nearby room. Karmelo sat alongside his legal team as the court prepared to receive the verdict.
A short while later, Austin’s twin brother, Hunter Metcalf, entered the courtroom and sat down with his parents, Jeff and Meagan Metcalf.
Shortly before 2:30 p.m., the jury returned with its decision. After fewer than three hours of deliberations, jurors found Karmelo guilty of murder.
Karmelo reportedly showed almost no visible reaction as the verdict was read aloud. His mother wept in the gallery, while supporters also appeared visibly shaken.
Across the courtroom, Hunter leaned forward in his seat as the verdict was announced. The case then moved immediately into sentencing.
Although Karmelo had been convicted of murder, the length of his sentence still hinged on another legal question.
The defense argued that the offense was committed under what Texas law calls ‘sudden passion.’ If jurors agreed, the punishment range would drop from five to 99 years down to between two and 20 years.
Prosecutors argued that standard did not apply. During sentencing arguments, Wirskye told jurors that sudden passion must arise directly from provocation by the person who was killed.
The state maintained that Karmelo, not Austin, had provoked the confrontation. At 4:40 p.m., jurors left the courtroom once more to deliberate Karmelo’s sentence.
Before the court proceedings wrapped up, Austin’s twin brother delivered one of the day’s most gut-wrenching victim impact statements.
Hunter asked Karmelo to look up and meet his eyes. Karmelo, who had been staring downward during the statements, complied.
‘You took a son, a brother, a friend, and my best friend, from this world,’ Hunter told him. ‘You took someone from me who was supposed to be an uncle, godfather to my kids. Now I want everything taken from you.’
Hunter said he had spent the past year trying to learn how to forgive and understand why his brother had to die. He also said he wakes up every single day knowing he can no longer pick up the phone and talk to Austin.
Hunter told Karmelo that his mother still cries herself to sleep every night. After finishing his statement, he stepped down from the witness stand and embraced friends.
At 7:30 p.m., jurors returned to the courtroom for the final decision of the day.
Judge Roach announced that the jury had rejected Karmelo’s sudden-passion claim. Jurors found that Austin’s death did not occur under the immediate influence of sudden passion arising from adequate cause.
They then sentenced Karmelo to 35 years in state prison. Under Texas law, Karmelo must serve at least half of that sentence before he becomes eligible for parole.
Moments before the sentence was read aloud, Karmelo appeared to be sobbing while members of his defense team tried to comfort him.
According to courtroom sketch artist Pat Lopez, Karmelo later glanced toward his parents and mouthed the words ‘I’m sorry’ before being led out of the courtroom. Judge Roach then ordered that Karmelo be taken into custody.
With the courtroom proceedings now complete, attention turns back to the confrontation at a Frisco track meet that prosecutors and defense attorneys spent months dissecting before a jury.
On Wednesday, April 2, 2025, the bleachers at Kuykendall Stadium in Frisco, Texas, were packed with students competing in the 11-5A district track meet. The event brought together more than a hundred student-athletes from eight Frisco Independent School District high schools, including Memorial High School and Centennial High School.
Under the tent set aside for Memorial High athletes, an interaction began between Austin, a junior at Memorial, and Karmelo, a student from Centennial. Witnesses told police that Karmelo, wearing a Centennial tracksuit, sat down in the wrong tent, and Austin told him to leave.
According to the police report, Karmelo opened his bag and said, ‘Touch me and see what happens.’ Statements from multiple students indicated that Austin either touched or attempted to move Karmelo. In the next instant, Karmelo allegedly pulled a knife from his bag and stabbed Austin once in the chest.
Witnesses said he then ran from the tent area. A black knife with blood on it was later recovered by officers in the bleachers. Coaches and certified athletic trainers responded immediately, performing CPR and applying pressure while waiting for emergency services to arrive.
Austin was rushed to a nearby hospital, where he was pronounced dead at 10:53 a.m. According to the official arrest report, the entire altercation — from the verbal exchange to the stabbing — lasted less than 30 seconds.
Police noted that more than 30 students and roughly half a dozen coaches from five schools were listed as witnesses, many of whom gave statements on-site.
Minutes after the stabbing, a Frisco school resource officer located Karmelo near the stadium. He matched descriptions provided by several student witnesses. According to the police report, officers spotted blood on his left middle finger and ordered him to raise his hands. He complied.
Before officers asked a single question, Karmelo began making unprompted statements. ‘I was protecting myself,’ he said. When one officer radioed that he had the alleged suspect in custody, Karmelo reportedly responded, ‘I’m not alleged, I did it.’
As he was walked to a patrol car, he added, ‘He put his hands on me. I told him not to.’ Witnesses at the scene described him as ‘crying hysterically.’ Officers noted he appeared visibly shaken throughout the arrest. Once seated in the back of the squad car, Karmelo asked if the victim was ‘going to be OK.’
He then asked officers whether the stabbing could be considered ‘self-defense.’ Another officer reported that Karmelo appeared emotional the entire time and repeated several of these statements without being prompted. He was taken to the Frisco City Jail and later transferred to the Collin County Jail.
Austin’s mother, Meagan, was at work in Grapevine when she got a phone call from Hunter. ‘He was screaming that Austin had been stabbed,’ she said in a televised interview. She drove straight to the hospital and arrived before the ambulance.
‘I saw them have him come out,’ she recalled. ‘He was on a lot of machines, and it didn’t take long for them to come in to say that he had passed.’ Her husband, Jeff, said Hunter had witnessed the stabbing firsthand and tried desperately to save his brother’s life.
‘[Hunter] was holding his hands on the hole trying to save his life,’ Jeff told CBS News Texas. ‘He told me, ‘I looked at him, his eyes — he was gone, he wasn’t breathing.” According to Meagan, CPR was performed after Austin was unresponsive for around five minutes.
‘They were able to revive him a little, but I think it was just, too little too late,’ she said. In a separate interview, Hunter also described what he witnessed.
‘I whipped my head around, and then all of a sudden I see him running down the bleachers just grabbing his chest… I put my hand on there, tried to make the bleeding stop, and I grabbed his head and I looked in his eyes. I just saw his soul leave, and it took my soul, too,’ he stated.
The family put out a written statement two days later, through a friend, thanking the community for their prayers and support. ‘We will entrust the detectives handling the investigation to determine the circumstances surrounding Austin’s passing,’ the statement read.
‘While our family, Hunter, and I prioritize commemorating and honoring Austin… we extend our gratitude to everyone who has supported us in numerous ways and helped sustain our family during this difficult time,’ it concluded.
More than a year after the fatal confrontation at a Frisco track meet, jurors answered the questions at the center of the case. Their verdict and sentencing decision brought the trial of Karmelo Anthony to a close.
