Las Vegas gunman Stephen Paddock reportedly researched hotels near Fenway Park in the run up to the deadliest shooting in recent American history. No hotel nearby the park commands a clear view of the Fenway stands. Officials briefed on the investigation's details spoke to reporters on the condition of anonymity Thursday, revealing Paddock researched Boston and booked a hotel room in Chicago overlooking Grant Park when the Lollapalooza music festival would have been going on. Boston police on Thursday issued a statement saying the department is aware Paddock likely researched the city and is working with federal authorities.
