The murder case crosses international boundaries, making it more complicated. Supporters of the victim understand that there are complex government protocols that must be followed.
Monica Beresford-Redman was found murdered in Cancun on April 8.
Her sisters and her friends marched in front of the United State Court House on Spring St. in downtown L.A. Thursday to step up pressure on the government to take action against Bruce Beresford-Redman.
"We are tired of waiting. It's not fair," said Jeane Burgos, one of Monica's sisters.
"It has been four months since she was murdered and it has been a month since Mexico has asked the United States to arrest him," said Alison Triessl, attorney for Monica's sisters.
Bruce Beresford-Redman, a television producer, is accused of killing Monica while on a family vacation in Cancun. Bruce fled back to the couple's home in Rancho Palos Verdes just as Mexican investigators were preparing to arrest him.
"We're asking our government to act," said Triessl. "And we're asking for them to do it now."
One month ago, the attorney general in Mexico sent a request to the U.S. State Department for a provisional arrest. The sisters say that request is now in the hands of the Department of Justice in Washington, D.C., not yet sent to Los Angeles.
A spokesman for the U.S. Attorney in Los Angeles confirms that, saying there is no extradition case pending in Los Angeles.
The Burgos sisters say the waiting is agony.
"It's like all the time in your head, and not letting you sleep, not letting you live your life like normally," said Carla Burgos. "Not just for me or my sister, but all her friends."
"Now we are demanding that the United States authorities just do what they have to do," said Jeane Burgos. "We are not asking for anything beyond what their duties are.
While the criminal case makes its way slowly through U.S. justice system, another case is pending in civil court. It involves the couple's two children. They remain in Bruce's household. The two sisters want custody of the kids.
