The men dressed as police officers stole about $200 million worth of art from the Isabella Stewart
Gardner Museum early this morning.
The two burglars (窃贼) knocked on a side door of the museum at about 1:15 am. They told the two
security guards who were on duty that there was a disturbance in the area. The guards then made the very
serious mistake of allowing the two men to go into the building. After they went in, the two burglars tied
the guards up with tape.
The two men spent about two hours in the museum. During that time, they stole 11 paintings and an
ancient Chinese vase. The stolen works included three paintings by Rembrandt.
A maintenance (保卫) worker discovered the two guards at about 7 am and called police. One of the
greatest losses was Rembrandt's works, "The Storm on the Sea of Galilee." It was a very popular attraction
at the museum and was one of the most valuable works stolen.
Museum officials said that the value of the stolen art is at least 200 million dollars, and may in fact be
much more. The true value of the paintings is unknown, because they have not been on the market for
nearly a century. According to law enforcement officials, this is considered to be the biggest theft ever in
the United States. Officials are waiting to see whether the burglars will demand a ransom for the paintings
or try to sell them to a private collector.
Museum officials and police are not sure why the burglars chose certain works and not others. There
are other paintings in the museum that are even more valuable than the ones that were stolen.
Special investigators are looking into the theft and the museum's security system. They believe that
this is a "professional job", because the people involved were well prepared and knew what they wanted.
Investigators have already questioned the museum's guards extensively. They would not give the names
or ages of the guards, but one investigator said the Gardner hires and trains its own security staff. So far,
the guards have not been identified as suspects in the case. An investigator said that anybody having any
information about the robbery should contact the Boston Police Department immediately.
