A computer was stolen from Blagojevich's attorney, but they say it probably didn't contain any evidence in the case.
Police made one arrest on weapons charges, but it wasn't related to the burglaries. Police said a shotgun was recovered at the home.
Burglars broke into the offices of Blagojevich attorney Samuel Adam and his son, Samuel Adam Jr., and took items that may contain information about Blagojevich's case. Those items include eight computers and a safe.
Blagojevich is charged with scheming to trade or sell President Barack Obama's former U.S. Senate seat.
Sam Adam Jr. said any evidence that may have been stolen was backed up on other computers in his offices.
"I can tell you this," Adam Jr. said. "We have all of the tapes themselves, and certainly and especially everything the governor has given us, and backed up onto a server in which we still have all of the material. We're trying to determine if one computer may or may not have had something on it. I don't think it did."
There was an alarm, but the burglars escaped.
Police say their investigation continues.
