Here is what we know so far about the hotel where Tamerlaidon Tsarnaev was staying.
The hotel is a private home and has been owned by a family since its creation in the late 1970s.
Tamerlan and Dzhokhar Tsarnaev were brothers who are still considered suspects in the killing of the two people they had been suspected of killing, a man and a woman, and a police officer, in Watertown, Massachusetts, in April 2015.
Tamerlazan Tsarnaev, the brother who is now the alleged Boston bomber, has not been seen since April 4 when he was seen in Cambridge, Massachusetts.
But the hotel has been under the scrutiny of US authorities since early May, when the FBI sent out a letter asking hotel staff to turn over documents related to the Tsarnaevs’ hotel.
There were also reports of hotel employees refusing to provide any information on Tamerlane Tsarnaev.
As of Sunday, the FBI had not responded to a request for comment.
US officials said on Monday that Tamerla Tsarnaev was not at the hotel and that he was not staying at the property.
However, the Boston Herald reported that a person at the resort had told them that Tsarnaev had been staying at a hotel nearby and that a security guard had checked him in.
Tatiana Tsarnaev, who lives in Cambridge with her husband, told The Boston Herald that her brother was at the home.
“I just wanted to give him a little time to think it over,” she said.
According to the Herald, Tashfeen Malik, a British citizen who lives with her father in Cambridge who was with Tamerlin Tsarnaev in the hotel, said she did not see the Tsarnaev brothers together.
She said the couple were “not really at it”.
“They didn’t really talk to each other,” she told the paper.
Malik said that Tashfedd, who is a Pakistani citizen who was born in Pakistan, had not visited the Boston area.
Another relative told the newspaper that Malik was with the Tsarnaev family for the past two years.
One of the people who lived in the house where Tashilak had been seen is Zainab Khosa, a woman who has lived with Tashlin since 2014.
Khosa told the Herald that she had heard Tashelin was living there but that she did a double take when she realised that she was in the same room.
On Sunday, she told local news station WCVB that she knew nothing about the Tsarnaev sisters, whom she described as “not nice people”.
Khosas father, Abdul Rashid Khan, was an employee of the hotel.
