Bruce Beresford-Redman's sister-in-law flew to Mexico today in an effort to get him extradited for the alleged murder of his wife.


According to Mexican officials, Jeane Burgos brought legal documentation to the Attorney General's Office in Quintana Roo in order to prove that Bruce is actually back in the United States.

Despite all the recent images of Bruce in L.A. -- authorities say the documentation is necessary because Mexican officials still have Beresford-Redman's passport. 

We're told Jeane's documentation could get the ball rolling for possible extradition -- however she was not able to meet with the prosecutor today.

Officials said they will set up a meeting with Jeane, but did not specify when that would happen.
