In ‘Boston Strangler’ case, patience was key

Donald Hayes was sitting at his desk in the Boston Police crime lab in the mid-1990s when the lieutenant running the cold case squad dropped a book in front of him: “The Boston Stranglers.”

Hayes had been a young boy north of Boston when a series of gruesome murders attributed to a serial killer terrified the region, and he knew only a little about the case. But he devoured the book — the latest to speculate that there were multiple killers — and soon shared Lieutenant Tim Murray’s desire to delve into a mystery that officials had more or less abandoned, even as it remained one of crime’s great enigmas.
