"The Boston Regional Intelligence Center is in contact with our local and federal law enforcement partners here and in Las Vegas and continues to monitor the situation".
Stephen Paddock may have considered locations in Chicago and Boston before he fired on a crowd of thousands from a hotel room in Las Vegas.
After learning that Fenway was possibly in the sights of the Las Vegas gunman, who researched the park and nearby hotels, police are going to have a bigger presence this weekend, with metal detectors and bag checks.
Paddock, who officials believe had an escape planned, fatally shot himself as a SWAT team descended on his hotel room.
Now, officials are looking into reports that Paddock also researched locations in Boston including Fenway Park and the Boston Center for Performing Arts. He did not, however, travel to Chicago nor did he book a hotel room near Fenway Park.
But William Evans said Thursday he could not confirm the report and had not been briefed on the matter.
Massachusetts Governor Charlie Baker issued a statement to NBC saying, '"We and many others are fully plugged in on that investigation, and there is no imminent threat to anything in Massachusetts'".
On Sunday, Fenway Park will be filled with Sox fans and heightened security, and it's a new reality that is getting mixed reviews.
We are aware of the media reports.
The Red Sox are asking fans to arrive early for all postseason games at Fenway Park to leave time for security screenings at the gates.
Stephen Paddock's potential targets included the most recent Lollapalooza festival in Chicago, which was held August 3 to August 6 in Grant Park, the officials said.
Paddock, 64, booked a room in a Chicago hotel but did not show up, the officials said.
Officials have said there is no credible threat to Boston.
A total of 58, excluding Paddock, were killed and almost 500 people were injured in the shooting.
