Investigators say forensic evidence undercut the account given after Savannah Copeland was killed.
KNOXVILLE, Tenn. — A teenager accused of killing 13-year-old Savannah Grace Copeland after an overnight meeting near a Powell trail is now facing adult-court charges that put his self-defense claim at the center of a Knox County murder case.
Malakiah Harris, now 16, was indicted April 8 on first-degree murder and two evidence-tampering counts. He was 15 when authorities say Savannah was stabbed near the Broadacres subdivision on Oct. 22, 2024. The indictment came after a juvenile judge transferred Harris to adult court, finding probable cause in a case shaped by autopsy findings, alleged statements and a disputed account of what happened in a wooded area near railroad tracks.
Harris told Knox County detectives that Savannah came toward him before the stabbing, according to testimony reported from court. “I turned around and she was coming at me,” he said in the statement described during the proceedings. Investigators said Harris claimed he took the knife from Savannah, wrapped her in a hold and stabbed her in the back. He said the stabbing continued until she stopped moving. Detectives have said the physical evidence did not match the idea that Savannah posed the kind of threat Harris described.
The medical evidence became one of the strongest parts of the prosecution’s request to move Harris out of juvenile court. Court records say Savannah suffered at least 93 stab wounds, with most wounds on her upper body. Judge Tim Irwin cited the severity of the injuries and other evidence when he ordered the case transferred to adult criminal court. The judge said there was probable cause to believe the killing was premeditated. Harris’ legal status changed after that ruling, and the later indictment replaced the earlier juvenile posture with adult criminal charges.
The events began before dawn after Savannah left home. Investigators have said she went to meet Harris and his younger brother so she could get a vape. The meeting area was near a pathway between railroad tracks and the Broadacres neighborhood swimming pool, a familiar local space in Powell. Savannah’s mother later reported her missing. Her father, Michael Copeland, said he searched after realizing she was gone and used cell phone information before finding her body in the woods. Authorities have said the case was treated as a homicide soon after the discovery.
After the stabbing, Harris and his younger brother went home, according to the account investigators presented in court. Prosecutors have said Harris told his brother, “All you need to know is it was self-defense.” Authorities have also said the younger brother later helped them find a knife believed to be connected to the killing. That alleged recovery supports the evidence-tampering counts now included in the adult indictment. The younger brother was friends with Savannah’s twin brother, a connection that added another layer to how the children’s families and social circles intersected before the killing.
Investigators also focused on what they say Harris said and sent after Savannah died. He allegedly texted a friend that the “deed is done” on the night of the killing. The next school day, authorities say, he told his girlfriend, “I got my first body.” He allegedly said he had stabbed someone but did not name Savannah. Prosecutors are expected to use those statements to challenge the self-defense claim and argue that Harris’ actions before and after the stabbing showed intent and awareness of guilt.
No public record has established a motive. Michael Copeland has said the possibility that no clear reason will emerge is one of the hardest parts of the case. He has also questioned whether others were involved or failed Savannah before the killing. For the family, the court record has become a painful map of the last hours of her life. For prosecutors and defense lawyers, the same record will be tested through motions, witness testimony and forensic evidence as the adult case moves forward.
Savannah was remembered as a Powell Middle School student who loved art and wanted to study forensic anthropology at the University of Tennessee. She also participated in cheerleading, gymnastics and karate, according to family accounts and memorials. Her obituary said she loved her family and friends. Those details have stayed prominent because relatives have pushed to keep her identity from being reduced to the number of wounds or the location where her body was found.
The case also led to action outside the courthouse. Tennessee lawmakers passed the Savannah Grace Copeland Act, which increased funding tied to child advocacy centers and forensic interviewers. Supporters framed the law as a way to strengthen services for children who need help during investigations and family crises. The law does not speak to Harris’ guilt or innocence, but it is one way Savannah’s death has had effects beyond the criminal docket in Knox County.
Harris remains presumed innocent unless proven guilty. The adult-court indictment means prosecutors can now pursue the first-degree murder charge in Knox County Criminal Court. The defense is expected to continue challenging the state’s case, including the account of what happened during the encounter. Hearings ahead are expected to set deadlines for evidence, motions and trial preparation.
The next stage will determine how jurors may eventually hear the self-defense claim, the autopsy findings and the alleged statements after Savannah’s death. For now, the case stands as an adult prosecution with no trial date publicly resolved.
