The artist, whose real name is Adidja Palmer, was tried and convicted as one of the killers of one Clive “Lizard” Williams.
Kartel maintained his innocence, but was not able to convince a jury. The jury came back with a guilty verdict after a mere two hours even though the trial took a whopping 65 days.
Kartel’s lawyer said they would vigorously appeal the decision and suggested the police were biased.
“We will not sit by and let this case of injustice score victory. We will be appealing the verdict given the many questionable police corruption in the case,” the lawyer said according to UrbanIslands.com.
Kartel was acquitted of the murder of Barrington “Bossie” Burton last year.
The body of Clive Williams was never found, but authorities maintain it happened in a house owned by Kartel.
Three other men, Shawn “Storm” Campbell, Kahira Jones, and André St John, were also found guilty in the murder.
Kartel faces life in prison.
