The crime, on June 19 at Haven Drugs on the county’s South Shore, appeared to have been a severe example of a national epidemic involving drugstore robberies by prescription drug addicts.
Those killed were Raymond A. Ferguson Jr., 45, the pharmacist; Jennifer Mejia, 17, the high school student, who worked part time at the store; and Jaime Taccetta, 33, and Bryon Sheffield, 71, both customers.
In a courtroom crammed with more than 30 relatives of the victims, Mr. Laffer, who appeared gaunt and pale and wore a green jumpsuit, calmly answered each of the prosecutor’s questions about that day. Asked, for instance, if he shot Ms. Taccetta in the back of the head, he said, “Yes, sir.”
After killing Ms. Taccetta, the prosecutor, John Collins, asked Mr. Laffer, did he go back to steal more drugs? He again replied, “Yes, sir.” As prosecutors recounted the grisly details, some relatives, who were seated in the first three rows of the courtroom, clutched one another’s hands and wiped away tears.
