In a case that has haunted Marion County for over a decade, Michael Shane Bargo Jr. , the youngest inmate ever sent to Florida’s death row, faces a new chapter of legal scrutiny after his second death sentence was upheld by the state’s highest court. The 34-year-old was convicted of the brutal murder of 15-year-old Seath Tyler Jackson, a crime so calculated and cold that a veteran judge called it the most premeditated he had ever seen in 32 years on the bench.
Bargo, now housed at Union Correctional Institution in Raiford, Florida, has spent years in a cell, pacing with persistent anxiety, according to mental health evaluations. His post-conviction proceedings remain ongoing, but the core of the case remains unchanged: a meticulously planned execution carried out by a group of young people who, for weeks, talked openly about killing a teenager who had dated a girl one of them was obsessed with.
The story begins on April 17, 2011, when Seath Jackson, a 15-year-old sophomore at Belleview High School, received a text message from his ex-girlfriend, Amber Wright. She told him she wanted to get back together. He was skeptical but hopeful.
He replied, and she lured him to a mobile home on Southeast 53rd Avenue in Summerfield, where a group of six people, including Bargo, was waiting. He never walked out alive.
Inside the house, Kyle Hooper, Amber’s older brother, and Justin Soto attacked Seath with a wooden axe handle and a piece of lumber. Seath, who had trained in mixed martial arts, fought back and nearly escaped out the door. But Bargo was waiting outside with a .
22 caliber Heritage revolver. He opened fire, hitting the teenager multiple times. Soto tackled Seath from behind, and the group dragged him back inside.
Bargo then ordered everyone out of the bathroom. He wanted to be alone with Seath. He wanted Seath to know who was killing him before he died.
He fired more shots into the boy’s body, including a final round to the face. Seath Tyler Jackson was dead.
What happened next is almost beyond comprehension. Bargo and Soto placed Seath’s body in a sleeping bag. To make it fit, Bargo broke the teenager’s kneecaps.
They carried the bag to a fire pit in the backyard. Hooper was assigned to tend the fire through the night, burning the remains for hours. Inside, Amber Wright, Charlie Ely, and others scrubbed the house with bleach, trying to erase the evidence.
Bargo and Amber Wright went to sleep. Hooper stood in the dark, alone, watching the fire until about 2:30 a. m.
on April 18. In the middle of the night, Bargo called 37-year-old James Havens, who had been at the house the night before and heard the planning. “The deed is done,” Bargo said.
Havens hung up and went back to sleep.
The next morning, Bargo and Havens loaded the remains into three five-gallon paint cans, weighted them with cinder blocks and cables, and drove to a remote rock quarry in Ocala. They dropped the cans into the water. Bargo watched until they sank.
Then he went back to Summerfield and spent the rest of the day telling anyone who would listen exactly what he had done. He was proud of it.
Seath’s mother, Sonya Jackson, had reported him missing after he failed to return home. She knew something was wrong because his last text to her was out of character. Investigators obtained search warrants for the mobile home, where forensic testing revealed blood in multiple locations, human tissue, and bone fragments in the fire pit.
A dive team recovered the three paint cans from the quarry. Ballistics linked Bargo’s revolver to a projectile found in the remains.
Six people were arrested on April 20, 2011. Over the following years, the cases moved through the courts. Charlie Ely was convicted and sentenced to life without parole.
Justin Soto pleaded guilty to life without parole. Amber Wright and Kyle Hooper, both under 18 at the time, were convicted of first-degree murder and sentenced to life without parole. Bargo was the only one eligible for the death penalty.
His first trial began in August 2013. The prosecution presented a mountain of evidence: witnesses who heard Bargo’s detailed confessions, forensic experts, and James Havens, who testified that he had left the house the night before because he didn’t want to be part of the planning, but then received Bargo’s call and did nothing. Bargo took the stand in his own defense, claiming he had left the house before the killing and only returned to find out what happened.
He said he didn’t report it because he feared the others would 𝓀𝒾𝓁𝓁 him.
The jury didn’t believe him. After eight days of testimony, they convicted him of first-degree murder with a firearm. During the penalty phase, his defense presented evidence of his troubled childhood: a chaotic home, a father who encouraged him to write hateful words about his mother in sidewalk chalk, diagnoses of bipolar disorder, schizoaffective disorder, frontal lobe brain damage, and a seizure disorder.
A clinical psychologist testified that Bargo’s decision-making was fundamentally compromised. The state’s expert countered that Bargo demonstrated organization, planning, and deliberate control throughout the murder and its aftermath. The jury recommended death by a vote of 10 to 2.
On December 13, 2013, Circuit Judge David Eddy, with 32 years on the bench, called the murder of Seath Jackson “the most cold, calculated, and premeditated case of murder I have ever seen.” He sentenced Bargo to death. At 21, Bargo became the youngest person on Florida’s death row.
But the legal battle wasn’t over. In 2017, the Florida Supreme Court vacated Bargo’s death sentence because the jury’s recommendation had not been unanimous. A second penalty phase was ordered.
In April 2019, a new jury heard the same evidence and returned a unanimous recommendation: death. The judge resentenced Bargo in September 2019. Bargo called the proceeding a “big circus.”
He said he had evidence of innocence that the court had refused to consider. The judge imposed the sentence.
On June 24, 2021, the Florida Supreme Court upheld his death sentence by a vote of 6 to 1. The ruling noted that the evidence of Bargo’s guilt was overwhelming and that the jury had properly weighed his mitigation against the brutality of the crime. Bargo’s post-conviction appeals are still working through the system, a process that can take years.
He remains at Union Correctional Institution, where he has been since December 2013.
Seath Tyler Jackson would have been 30 years old this year. He was a funny, loyal teenager who loved animals, trained in mixed martial arts, and dreamed of competing. He was bullied but refused to become a bully.
He was killed by a group of people who spent weeks planning his death, who lured him with the promise of reconciliation, who beat him, shot him, burned his body, and dumped his remains in a quarry. His mother, Sonya, sat through every trial, every hearing, every sentencing, watching the system decide what her son’s life was worth.
Now, the question that lingers is one that defies easy answers. Michael Bargo grew up in documented chaos, with brain damage, untreated mental illness, and a father who taught him to hate his mother. A jury heard all of that mitigation twice and voted for death both times.
A judge with three decades of experience called this the most cold and calculated case he had ever seen. Does a childhood like Bargo’s explain what he did to Seath Jackson? Or is there a point at which no explanation reaches?
The answer may never be fully clear, but the legal system has spoken: Michael Shane Bargo Jr. is sentenced to die for the murder of Seath Tyler Jackson. The process continues, and the family of a 15-year-old boy who loved animals and made people laugh waits for a final resolution that may still be years away.
