The man responsible for the brutal killing and dismemberment of beloved Greenbelt teacher Mariame Toure Sylla will spend the rest of his life behind bars. On Friday, 35-year-old Harold Landon III was sentenced to life in prison without the possibility of parole for the July 2023 murder of Sylla, 59.
A jury had previously found him guilty of first-degree murder in June. Sylla was a respected educator at the Dora Kennedy French Immersion School, where she was cherished by students, parents, and colleagues alike. She was known for her warmth, faith, and dedication to her work.
When she disappeared during an evening walk in Greenbelt Park, the local community immediately organized search efforts. Days later, the discovery of her dismembered body sent shockwaves through Prince George’s County, as ABC affiliate WJLA.
“This woman was a good person. She cared about people. She was religious. She was a believer and she loved her children — the children she taught,” said Prince George’s County Executive Aisha Braveboy, who also served as the state’s attorney at the time of Sylla’s murder.
Parts of Sylla’s remains were discovered along Old Alexandria Ferry Road in Clinton, Maryland, though investigators said it took weeks to confirm her identity. Some of her remains have still not been found. Landon, who lived in the same neighborhood as Sylla but did not know her personally, was arrested and charged with murder soon after.
Prosecutors argued that he killed the elementary school teacher as part of an unexplainable, violent impulse. “I don’t think we’ll ever know his true motive,” Braveboy said. “What we do know is that he did it, that he was clear-minded that he did it, and he was very calculating in trying to cover up what he had done.”
During sentencing, Judge Carol Cordere agreed with that assessment and imposed the maximum penalty allowed by law — life without parole. Current State’s Attorney Tara Jackson said the punishment reflects the deep loss Sylla’s death caused, according to The Washington Post.
“While today’s sentence cannot return Ms. Sylla to us, it stands as a testament to her value to this community — to Prince George’s County,” Jackson said. Sylla’s sister, Fatima, and son, Mohamad, appeared virtually in court from the Ivory Coast, both urging the judge to deliver the harshest sentence.
“He should never walk free again,” Fatima said. When given the opportunity to speak, Landon declined. He whispered briefly to his attorney, shrugged, and said nothing — no apology, no explanation, not a single word.
