The same firearm used to shoot Randolph Lightbourne was used to murder two other men, the Supreme Court was told this morning.Both Dekimo Martin, 24, and 29-year-old Colford Ferguson were gunned down in Sandys using the same firearm that wounded Mr Lightbourne last July, the court heard.Marico Bassett, 20, is on trial for the attempted murder of Mr Lightbourne, using a firearm to commit an indictable offence and the possession of two bullets. He denies all charges.In court today, gang expert Sergeant Alexander Rollin said he believed Mr Bassett was associated with the Somerset-based gang Money Over Bitches (MOB).He explained that to his understanding, gang members could be defined as ‘shot callers,’ who determines what course the gang should take if someone has disrespected the gang, and ‘soldiers’, who carry out the instructions.“I would put the defendant as the soldier category,” Sgt Rollins said.Under cross-examination by defence lawyer Marc Daniels, Sgt Rollins said he could not confirm if the defendant had been initiated in the gang, but that he had seen Mr Bassett with known gang members. He said he could not give details about how he received his information.Detective Constable Leroy Mathurin also took the stand, saying that overseas tests had linked the bullets found at the crime scene and inside Mr Lightbourne to the same gun connected to several other firearms cases which occurred in the west end, including two fatal shootings.This afternoon, the defence started its case by calling to the stand the defendant’s mother Sharon Bassett, who described an early morning raid on her home as a ‘horror’.She said she had spoken with her son about the shooting when she returned home from work on the day of the incident, but Crown counsel Carrington Mahoney questioned why she did not mention the conversation to police.She responded that she was never asked about her son, and that the police were only concerned about a motorcycle which she said the family had recently sold.The trial continues.
