KINGSTON, Jamaica—Barbadian businessman Omar Collymore, who is serving a double life sentence for masterminding the January 2018 murder of his then-wife, Simone Campbell-Collymore, and cab driver Winston Walters, will on Wednesday be engulfed in a fresh trial.

This time, to answer charges that he conspired to murder another woman with whom he was in a relationship.

Details of the alleged plot will be unveiled on Wednesday when the Crown lays out its case against Collymore, who, alongside his co-accused Carey Jonas, Dwayne Pink, Michael Adams and Shaquille Edwards, is all facing charges of illegal possession of a firearm, shooting with intent and conspiracy to murder.
