The jury is expected to hear testimony from two expert witnesses, Joseph Simmonds, who is an official from telecommunications company Digicel, and police detective Heather Forrest.
The jury has been out of the courtroom as the court heard sensitive testimony from witnesses.
Among those who were called to the witness stand was cyber crimes expert Detective Sergeant Patrick Linton, the former head of the Police Forensic and Cybercrimes Unit at the Organised Crime Investigation Division.
The police had reported that they seized cellphones and other materials which showed video and audio recordings linking Vybz Kartel and his co-defendants to the killing.
Yesterday, Supreme Court judge Justice Lennox Campbell, who is presiding at the trial, ruled to allow the jury to be presented with evidence including that taken from mobile phones.
Kartel is jointly charged with fellow entertainer Shawn Campbell also known as Shawn Storm, Kahira Jones, Shane Williams and Andre St John for the August 16, 2011 murder of Clive ‘Lizard’ Williams.
Williams was allegedly killed in relation to two missing guns.
