Three-time convicted murderer Kaniel Martin is in trouble with the law after he allegedly stabbed fellow inmate Rashawn Shabbaz in the early hours of Friday morning.

High Court judge Justice Richard Floyd has reserved his decision against Avie Howell and Kaniel Martin, who were convicted for killing three people.

High Court officials and the police will investigate allegations that relatives of one of the two men convicted of the murders of a honeymooning couple and a shopkeeper made threats after the guilty verdict, well-placed sources said.

A jury of eight men and four women is expected to be asked to determine whether Avie Howell and Kaniel Martin are guilty of killing British couple Benjamin and Dr Catherine Mullany three years ago on this very date.

“They brought no evidence of fingerprints to match Kaniel Martin. They brought no evidence of footprints to match Kaniel Martin. They brought no evidence of GSR (gunshot residue) to match Kaniel Martin.”

After 31 days of intense testimony, the prosecution and defence rested their cases in the High Court yesterday, bringing the court one step closer to allowing the jury to deliberate the fate of co-accused Avie Howell and Kaniel Martin in the triple murder trial against them.

Yet another telecommunications expert testified about exchange of phone calls and location of the users – accused murderers Avie Howell and Kaniel Martin – as the triple murder case against them continued in the High Court yesterday.

Dr Christopher Moyneham, the UK expert in recovering gunshot residue (GSR), yesterday said the residue found on clothing belonging to murder accused Avie Howell and Kaniel Martin’s clothing ranged from low to moderate on different garments and in some instances could have been inadvertently picked up.

Forensic testing on the blue and white bandana recovered from the scene where shopkeeper Woneta Anderson was murdered has shown the presence of DNA belonging to accused Avie Howell, who is on joint trial with Kaniel Martin for the August 2008 killing and the July 2008 murder of British couple Benjamin and Dr Catherine Mullany.

The lead forensic scientist at the Metropolitan Police Services (MPS) New Scotland Yard yesterday testified that a bloodstained shoe print found on the scene where shopkeeper Woneta Anderson was killed was “probably” made by shoes taken from murder accused Avie Howell.
