DETAILS: Vybz Kartel Trial: Jury Deliberation Next Week

This morning Taylor brought up a case dated back to 1995 in which the retired cop appeared where the court said his opinion deprived the court of probative feature due to lack of photographic record.

The retired cop says he did not remember the case, but Jeremy Taylor showed him the judgement.

Justice Lennox Campbell asked the witness if photographic enlargement help the court understand how he came to his opinion and the expert witness said yes. Major also reference several material which he used to come to his conclusion.

Jeremy Taylor also argued in court that the signature in the letter allegedly written by the prosecution star witness Lamar Chow and sent to the Public Defender was missing a “W.”

But Karl Major insist that there is a “W” in the signature.

The prosecution is arguing that the letter is a forgery, but the defense is saying it is legitimate. The letter is one critical piece of evidence the defense has in their favor that could significantly damaged the prosecution’s case.

Kartel, born Adidja Palmer, Shawn “Storm” Campbell, Kahira Jones, André St John, and Shane Williams are on trial for the alleged murder of Clive “Lizard” Williams, whose body has yet to be found.

Authorities say Williams was killed over two missing firearms belonging to Vybz Kartel on August 16, 2011 at a house in Havendale.
