By Andrea Shalal WASHINGTON (Reuters) - Lawmakers will examine possible shortcomings in law enforcement or intelligence in the case of a Tennessee shooting that killed five servicemen, a top Republican said on Sunday, adding that the case may be linked to Islamic State. Representative Mike McCaul, who heads the U.S. House of Representatives homeland security committee, told ABC's "This Week" program the case highlighted growing concern about Internet-based directives from Islamic State leaders in Syria. Senator Dianne Feinstein, the top Democrat on the Senate Intelligence Committee, said the gunman appeared to be a "classic lone wolf," but said it was difficult to know for sure given new encryption applications available to terrorists.
It takes a mere 10 minutes by boat to navigate to New York City's Hart Island, one of the United States' largest paupers' cemetery. Grable, 64, was one of a few dozen mourners who for the first time walked across the barren island on Sunday. For years, city rules confined mourners to a small memorial gazebo, furnished with a few benches and tucked away on an island's corner.
