New York - Investigators are looking at disgruntled former Goldman Sachs workers as possible suspects in their efforts to find the person who mailed dozens of letters threatening the investment firm last month, federal officials said Tuesday.
The letters, handwritten in red ink on lined, loose leaf paper, dealt a terse threat: "Hundreds will die. We are inside. You cannot stop us," authorities said.
The warning was signed, "A.Q.U.S.A."
Investigators have compiled a list of potential suspects, considered "people of interest," which includes former employees, said Tom Boyle, a spokesman for the U.S. Postal Service.
"We are investigating certain individuals either to remove them from the list or to gather more information on them," Boyle said. He said that no arrest is imminent.[ap]
