Investigators are gathering clues in their probe of the circumstances surrounding the killing of 82 year old Iciline McFarlane and her two grand-daughters by gunmen in Tryall Heights, Spanish Town, St. Catherine Sunday afternoon.
The girls have been identified as six year old Mishane McFarlane and 10 year old Christina McFarlane.
Two of the victims died at the scene and the other in hospital.
Superintendent Steve Brown, ground commander of the St. Catherine North Enhanced Security Measure, told Radio Jamaica News that they were shot at home.
He said the home invasion and killings, carried out by "gunmen traveling in a motor vehicle," took place "between 3:30 and four o'clock, thereabouts,"
He said detectives are following leads in their probe.
Deputy Commissioner in charge of Crime, Fitz Bailey, who visited the scene, told our correspondent that security in Tryall Heights will be increased as a result of the killings.
"What I saw is just some gruesome act, that was perpetrated by... well, criminals," DCP Bailey exclaimed as he seemingly struggled to exercise restraint in his characterisation of the perpetrators.
The society has a responsibility to "protect our females and our children, and our elderly," he stressed, while bemoaning the absence of any such shield in the face of "such act on the elderly and children."
This, he said, "speaks to the fact that we have failed as a society."
Denise daley, MP for the constituency in which the killings occurred, expressed outrage and condemned the killers.
