Karmelo Anthony is on trial in McKinney, Texas, accused in the fatal stabbing of 17-year-old Austin Metcalf at a high school track meet in Frisco.
The case, widely searched under the query karmelo anthony, has drawn national attention as the defence rested and the jury prepared to begin deliberations.
Judge John Roach Jr ordered the jury sequestered in a hotel, isolating jurors from television, phones and social media as they prepare to weigh a verdict.
Jurors are expected to receive detailed legal instructions before considering whether Anthony, now 19, is guilty of murder or acted in self-defence at the time.
Court testimony described the April 2 incident beginning when Anthony, a student at Centennial High School, sat under another school's tent during heavy rain.
Witnesses said tensions rose after Austin Metcalf, a Memorial High School student, asked Anthony to leave the tent area, and accounts of the confrontation varied significantly.
The trial record includes 911 recordings, video of the altercation and graphic images shown to jurors, with family members of both Metcalf and Anthony attending proceedings.
One witness testified that he heard Anthony say, "I told him not to touch me," although that witness later acknowledged he did not see the full incident.
Prosecutors have argued Anthony was the aggressor and had chances to avoid the fight, while the defence emphasised witness inconsistencies and Anthony's claim of self-defence.
Anthony has pleaded not guilty and faces a sentence ranging from five years to life under Texas law after being tried as an adult despite being 17 at the time.
Social Media Reaction And Courtroom Warnings
Online discussion has focused both on the facts presented in court and on speculation, including viral claims about a family connection to former NBA star Carmelo Anthony.
There is no evidence or public record indicating any family link between the two, and reporters say the confusion stems from similar names amplified by viral posts.
Before the court adjourned, Judge Roach warned jurors not to search for information or discuss the case outside deliberations, stressing reliance on admitted evidence only.
As closing arguments approach, the jury remains sequestered while deliberations will decide whether evidence supports a murder conviction or acceptance of the self-defence claim.
