The State of Texas vs Karmelo Anthony

In last week’s episode, I explored the tragic death of 17-year-old Austin Metcalf and the events that unfolded during a high school track meet in Frisco, Texas. This week, I’m following the case into the courtroom as we examine The State of Texas vs. Karmelo Anthony. During this episode, I’ll walk through the key moments of the trial, the arguments presented by both the prosecution and defense, and the jury’s ultimate decision. We’ll discuss the self-defense claim raised by the defense, the testimony presented during the proceedings, and the factors that may have influenced the outcome. I’ll also review the sentencing phase and the emotional victim impact statements delivered by Austin’s family. As always, my goal is not to sensationalize tragedy, but to help listeners better understand the investigative and legal processes that follow a violent death. Cases like this often generate strong opinions and intense public discussion, but inside the courtroom, decisions must be based on evidence, testimony, and the law. Join me as we take a closer look at one of the most closely watched criminal trials in recent Texas history and examine the legal journey from a fatal encounter to a murder conviction. EPISODE TRANSCRIPT: 00:06 Welcome to Pushing Up Lilies. I’m your host, Julie Mattson. Pushing Up Lilies is a weekly true crime podcast with spine-tingling, unusual, and terrifyingly true stories from my perspective as a forensic death investigator and a sexual assault nurse examiner.  00:24 Do I have some stories for you? Are you ready? Hey guys, welcome to another episode of Pushing Up Lilies. Super excited. This is my 202nd episode. And I just want to thank everyone at the Louisville Police Department.  00:48 I spoke with their volunteers last night and I do it frequently, probably, I don’t know, once or twice a year. But it is so fun to go and visit with them. They love to hear about death investigations and exactly what death investigators do.  01:06 And it’s such an amazing group of people. And they donate so much of their time. Big shout out to that group for having me and making me feel welcome. I went into the new Louisville Police Department and it’s beautiful.  01:20 I’ve not been into the new building yet. I know that many of the officers were wondering how long it was going to take before they could get moved in, but it’s really pretty. Thank you again. I appreciate y’all so much.  01:33 This week, I need to touch on the Austin Metcalf case. I covered the Karmelo Anthony trial last week, and I just need to give y’all updates because this is in my area. It’s right down the street. So last week we talked about Karmelo Anthony, a student in Centennial High School here in Frisco.  01:55 He was charged with first degree murder back in April of 2025 for stabbing 17-year-old Austin Metcalf during a high school track meet. And one of the biggest controversies occurred before the testimony even began.  02:10 This was when the jury was chosen because the final jury actually consisted of 12 jurors and there were six alternates, but there were no black jurors seated despite Karmelo Anthony being black. Not a big deal, right, to me, just because color to me is not important.  02:33 But defense attorneys actually challenged the prosecution’s removal of several black prospective jurors, arguing that there was racial bias. Prosecutors actually stated that those jurors were struck because they were educators.  02:50 It had nothing to do with race. And the judge sided with the prosecution. And of course, outside of the courthouse, supporters of Anthony and Metcalf gathered, and tensions ran a little bit high. Wouldn’t want to be in the area during that time.  03:10 On day one, the opening statements took place. The lead prosecutor told jurors that they would see evidence showing that Anthony actually initiated the confrontation and used a concealed knife during what would have been a minor disagreement over seating under a team tent.  03:32 Now, prosecutors argued that the stabbing was intentional and that it was not at all justified. Now, as far as the defense position, defense attorney Mike Howard said that Anthony found himself surrounded and frightened.  03:51 And the defense told jurors that Anthony acted on a split second during a chaotic confrontation and that he believed he was in danger. Their theme from the very beginning was self-defense. The prosecution’s first witness was Mark Porter, and he’s a forensic video analyst.  04:13 Porter actually walked jurors through the surveillance footage from multiple cameras around the stadium. Prosecutors argued the footage showed Anthony entering the tent area, a confrontation occurring, and then Anthony leaving immediately afterwards.  04:33 Now, jurors also saw body camera footage and surveillance evidence at that time. On day two, eyewitnesses took the stand. There were several teenage witnesses and friends of Austin Metcalf’s who testified.  04:51 According to reports, those witnesses consistently described Karmelo Anthony as the aggressor. Their testimony centered really on the argument beneath the tent, Anthony’s refusal to move, and the rapid escalation that followed after that.  05:11 Multiple witnesses described Anthony producing a knife during the confrontation. This was one of the most emotional days of the testimony because many witnesses personally knew Austin Metcalfe. And so you can only imagine how difficult that would be, especially for kids in high school.  05:31 Jurors also heard details about Austin’s final moments after the stabbing, which was also, I’m sure, very difficult to hear. Now, day three, the prosecution continued calling witnesses. Jurors heard from investigators, law enforcement officers, coaches, and also others involved in the aftermath immediately after the stabbing.  05:57 Now, one significant piece of testimony involved Anthony’s statements after the stabbing and body camera footage showed Anthony telling officers he put his hands on me. Now, that statement really became important because the defense argued it supported self-defense, while prosecutors argued that it did not justify

Inside the Crime that Shook a Community – Part Three

In this episode of Pushing Up Lilies, I continue Inside the Crime That Shook a Community with Part Three, focusing on the trial of the man responsible for the death of 7-year-old Athena Strand. This is the part of the story where the legal process begins… but that doesn’t make it any easier. As I walk through the courtroom proceedings, I do so with the same care and intention, because behind every testimony, every piece of evidence, and every legal argument is a family still living with unimaginable loss. Trials are meant to bring answers.They’re meant to bring accountability. But they don’t always bring peace. From an investigative perspective, I also share insight into what happens when a case moves from the scene into the courtroom, how evidence is presented, how timelines are reconstructed, and how the justice system works to piece together the truth in a way that can be understood by a jury. And while this part of the story focuses on the trial…I want to be very clear about something. This is not about the man who committed the crime. It is still about Athena. Her life.Her memory.And the impact she left behind. This episode contains discussion of child violence, courtroom testimony, and sensitive details surrounding the case. Please take care of yourself while listening, and step away if you need to. EPISODE TRANSCRIPT:  00:06 Welcome to Pushing Up Lilies. I’m your host, Julie Mattson. Pushing Up Lilies is a weekly true crime podcast with spine-tingling, unusual, and terrifyingly true stories from my perspective as a forensic death investigator and a sexual assault nurse examiner.  00:24 Do I have some stories for you? Are you ready? Hey guys, welcome to another episode of Pushing Up Lilies. This is your host, Julie Mattson. I can’t even tell you how excited I am about CrimeCon. I have never been as a spectator, an exhibitor, or a creator.  00:47 So, I’m super excited to get to go this year. I’m an exhibitor. I could not get on Creator’s Row. I understand that that’s rather difficult. And so, I’m going as an exhibitor, kind of get my foot in the door.  00:58 And I’m hoping to go to Crime Cruise also in November, which travels out of Florida. So if you are planning on going, stop and see me. I would love to visit with you. I’ll have all my merch there. We’re going to do the canvas bags, pens, stickers, t-shirts, hoodies, and poker chips.  01:18 My chips are clay. I think I told y’all I ordered the clay ones. I wanted it to be like a real souvenir and not something that was easy to throw away and super lightweight. So anyway, they’re clay. I’m excited about those.  01:32 They’re cute. They’ve got like my QR code on the back. So, you can go straight to my website. But my merch will be available on the website soon. It’s all new designed stuff that will be available at CrimeCon.  01:46 The first time it’s been available was at Beyond the Crime when we went to New Mexico last month. So, it’s all kind of new design and we sold a lot of merch at Beyond the Crime. So that was so much fun.  01:59 I’m really looking forward to Crime Con. Three days, I think last year they said 6,000 people attended Caesar’s Palace and it’s May 29th through 31st and so super excited. Look forward to seeing you there.  02:13 This week, I want to talk a little more about the Athena Strand case. Again, it’s not one that I really wanted to cover, but I wanted to make sure that I covered just the facts, not guessing what’s happening or guessing what’s going on in people’s heads, but just kind of covering the story and what’s going on.  02:34 So, this episode is a heavy one. And before I get into it, again, I want to say out loud that there are a lot of cases that I cover and you just move on. And there are ones that kind of stay with you even after I stop recording.  02:48 And this is one of those because at the center of everything, we’re about to talk about, it’s not just a case and it’s not just evidence and it’s not just a defendant sitting in the courtroom. It’s a little girl.  02:59 Athena was only seven. What we’re walking through today is the sentencing phase of Tanner Horner’s trial. Now, he already pled guilty, so there’s no question about whether or not he did this. That part is done.  03:12 So now the jury is left with one decision. And it’s one of the hardest decisions any jury will ever have to make. Is he going to get life in prison without parole or the death penalty? And to get there, unfortunately, they had to sit through days of testimony and listen to witnesses who reminded the courtroom who Athena was.  03:36 Some of them walked through exactly what happened and others kind of tried to explain who Tanner Horner is and how he became the person sitting at the defense table. Now, I want to cover a little bit about like what happened during the trial days because like me, I work.  03:55 I can’t sit and watch the trial all day long. I would love to because it’s super interesting. And I did watch the O.J. Simpson trial. I remember back in the day, but that was before life started lifing.  04:09 On the first day, the tone was set pretty much. Tanner Horner stood up. He pleaded guilty. There was no drawn out trial over guilt and no uncertainty at all. It was just acknowledgement, basically. In a way, that shifts the entire weight of the trial because now the jury’s not trying to figure out if he did it.  04:31 They’re just trying to figure out what to do with the truth.

Where It All Began: Julie’s Story – Host of Pushing Up Lilies
byJulie Mattson

Who am I, and how did I end up investigating death for a living?

In this very first episode of Pushing Up Lilies, I’m sharing my story, from my path into nursing to becoming a Forensic Nurse Death Investigator. I’ll talk about what drew me to this unique profession, what it’s really like to investigate deaths, and why I felt called to create this podcast.

Over the years, I’ve responded to countless death scenes, worked alongside law enforcement, medical examiners, and families experiencing unimaginable loss. Those experiences have taught me that every death has a story, and understanding that story requires compassion, science, careful investigation, and sometimes asking difficult questions.

Pushing Up Lilies was created to give listeners an honest look behind the scenes of death investigation. Whether you’re fascinated by forensic science, curious about how cases are solved, or simply interested in the realities of this profession, I hope this podcast helps educate, inspire, and answer questions you’ve always wondered about.

If you’re new here, welcome. This episode is the perfect place to begin. If you’ve been listening for a while, thank you for being part of this journey. I’m so glad you’re here.

Join me as I share the story behind the microphone, and the path that led me to Pushing Up Lilies.
