There may be more trouble on the horizon for jailed Vybz Kartel.

The dancehall DJ, who is already facing charges of murder, conspiracy to murder and illegal possession of a firearm, could be at the centre of police investigations into two additional murders, according to police sources.

The news came as the artiste, whose real name is Adija Palmer, appeared in the Gun Court division of the Corporate Area Resident Magistrate’s Court to answer to charges against him.

Palmer entered a plea of not guilty and his lawyers are expected to seek bail for him when he returns to court today.

Palmer has been charged in connection with the murder of Barrington ‘Bossie’ Burton, a 27-year-old businessman/promoter of St Catherine. Burton was murdered while standing with friends along Walker’s Avenue in Gregory Park.

Attorney Tom Tavares-Finson told reporters that during the hearing, which was closed to the public, the court was informed that two men are to be charged jointly with Palmer for Burton’s murder.

Palmer was remanded into police custody until today when the case against him will be motioned for a bail application to be heard.

Additionally the court was told that statements have been served on the defence by the prosecution.

The artiste was arrested two weeks ago, along with three other persons, at a hotel in New Kingston by cops from the Flying Squad.

Yesterday morning a throng of fans bearing posters with the artiste’s likeness converged on the Half-Way-Tree Police Station shouting pro-Kartel slogans and chanting, “Free the world boss,” using a title the DeeJay has bestowed upon himself.

The peaceful crowd, comprising mainly young women, were of the view that Palmer had been set-up. The group stayed late into the afternoon hoping to catch a glimpse of the artiste while he was being transported from the court’s lockup.
