johng,
Unfortunately I dont feel you are fully understanding the most important piece of the current puzzle, which is the lotto scam. When the news reports about "no logical motives" for these latest acts, as jon c. pointed out, your location and perception can mean everything. For those of us living daily in Jamaica, we now take it mean that it is probably part of the lotto scam. The police may not have all the proof yet to make that announcement or even be withholding information as to not interfere with an investigation.
From LoopJamaica, their "Lotto Scam" section has 4 pages of headlines such as the following:
Over a dozen alleged lotto scammers to face court this month September 3, 2016

About a year ago, the USA stated that the Jamaican lottery scam is bigger than drug trade. To quote the article:
"The United States Embassy has described the lottery scam in Jamaica as so organized that it is bigger than the drug trade.
The statement effectively becomes the latest warning about Jamaica issued online by the Embassy.
"The lottery scam in Jamaica has morphed into an organized crime wave bigger than drugs," stated a tweet this month by the US Embassy with a link to a CNN story about an 81-year-old Tennessee native committing suicide after he was bilked out of thousands of United States dollars by Jamaican lottery scammers.
The scam is wreaking havoc in both countries. Hundreds of senior citizens have lost life savings to the scam in the US while, in Jamaica, the scam has led to a wave of murders in Western Jamaica."

You can choose to give more credence to simple "greed fueled by foreign intervention, political manipulation leading to the importation of thousands of guns and violence and the evolution of the ganja trade into cocaine, especially crack and also heroin and other addictive and violence provoking drugs." But that goes against the facts as both the USA and Jamaica know them to be.
The lotto scam is the main reason the FBI now has an active office in the US Embassy in Kingston.
