Court spokeswoman Kathy Arberg told CNN Thursday no one was home when the burglary occurred May 4, which was discovered by a housekeeper.
This is the second robbery Breyer, 73, has been a victim of this year. A man wielding a machete broke into Breyer's Caribbean vacation home on Feb. 9, taking $1,000.
Breyer's misfortunes aren't the first to befall a Supreme Court Justice. Justice David Souter was assaulted in 2004 while jogging, and Justice Ruth Bader Ginsberg had her purse stolen in 1996.
Justices rely on the court security team for protection; however, when they are outside of the Washington area, the U.S. Marshals Service is responsible for their security.
