Police say relatives called emergency crews after JK Athree asked for help hiding a body.
SIOUX CITY, Iowa — Relatives of a Sioux City teenager called 911 on New Year’s Day after he allegedly came home from a parked car and said a dead body was outside, turning a family confrontation into a murder investigation.
The call brought police to 409 Cook St. around 11:20 a.m., where officers found 43-year-old Jermel Ellington in a car in an alley. JK Athree, who was 17 then and is now 18, was arrested at the residence and later charged with first-degree murder. The case now sits in adult court, where a judge has refused to move it to juvenile jurisdiction and defense lawyers are trying to keep Athree’s early statements away from a future jury.
Police say the most important decision after the stabbing came inside the home. Athree allegedly told family members there was a dead body outside and wanted help hiding things connected to what had happened. His relatives did not agree, according to law enforcement accounts. They called emergency services. When they did, Athree allegedly became aggressive and tried to flee before officers detained him. Authorities have not publicly named the relatives or described exactly what each person said during the 911 call. But that call became the point when an alleged private request to conceal a killing became an official response by police and medics.
Outside the residence, officers found Ellington in the car. He had 16 stab wounds and was taken to a hospital, where he was pronounced dead. Police initially described the incident as isolated and said there was no ongoing threat to the public. They also said Athree and Ellington knew each other. The location, a car parked in an alley near a home, has remained central to the public account of the case because investigators say the killing happened before Athree walked inside and spoke with his family. The exact timing between the stabbing, the family’s call and the arrival of officers has not been fully detailed in public records.
According to court reporting, investigators believe Athree stayed in the vehicle with Ellington for more than an hour after the stabbing and listened to music while Ellington was dead. That detail has become one of the case’s starkest allegations because it separates the violence itself from the later call for help. Police say the stabbing followed a brief exchange of words while Athree, Ellington and others were in the parked car. Ellington had been struck in several areas, including the thigh, back, neck and chest. The people who were with them in or near the car have not been fully identified in public reports, and authorities have not released a complete witness list.
The history between Athree and Ellington may become a major part of any trial. Investigators have described an earlier feud that began months before the killing, when Ellington allegedly caught an intoxicated Athree trying to break into vehicles. During that earlier confrontation, Ellington stabbed Athree with a screwdriver. Prosecutors may use the prior conflict to explain why the two men argued again on Jan. 1. Defense lawyers may point to the same history for a different reason, including possible fear, intoxication or a disputed state of mind. The court record so far shows that both sides see the events before New Year’s Day as more than background.
Athree’s case first raised a major question about where he should be tried. Because he was 17 when Ellington died, the defense sought to have the matter moved to juvenile court. District Judge Robert D. Tiefenthaler rejected that request. In his ruling, the judge said juvenile court would not have authority over Athree long enough to provide meaningful supervision, treatment or protection for the community. He said adult court offered the better chance for rehabilitation because services could last longer. The ruling did not decide guilt or innocence. It decided that Athree would continue facing the first-degree murder charge in district court as an adult defendant.
The next fight centers on statements Athree allegedly gave to police. Public defender Brendan Kelly has argued that the statements should be suppressed because the waiver of rights was flawed. The defense says Athree’s mother did not speak English as her native language and was not given an interpreter before rights were waived. The motion says she needed to understand not only Athree’s rights but also her own right to confer with and advise him about whether he should speak without counsel. The defense also says Athree was intoxicated when he made the statements, making them involuntary. Prosecutors are expected to argue the statements were legally obtained.
The suppression issue matters because the state’s case could look different depending on the judge’s ruling. Statements by a defendant can help prosecutors prove intent, sequence and awareness after an alleged killing. Without them, the prosecution may still have evidence from the scene, the medical findings, witnesses, the 911 response and the circumstances at the home. The defense has already signaled several possible trial themes, including self-defense, insanity, intoxication and diminished responsibility. Those defenses do not all carry the same legal meaning, and the court will decide before or during trial what jurors may consider under Iowa law.
The human frame of the case remains the split between two responses on Jan. 1. Police allege Athree wanted help hiding evidence after Ellington was fatally stabbed. His family instead called 911. That decision brought officers to the alley, brought medical crews to Ellington and placed Athree in custody before he could leave the residence, according to law enforcement. It also gave investigators an immediate account of what happened inside the home after the stabbing. Authorities have not said whether the family members will testify, but their actions are likely to be part of the prosecution’s timeline.
Athree has pleaded not guilty and remains in the Woodbury County Jail on a $500,000 bond. His trial is set for Nov. 17, 2026, with the court expected to resolve the statement dispute before jurors hear evidence.
