LOS ANGELES - Lawyers for a reality TV producer charged with killing his wife in Mexico attacked the investigation Wednesday and promised a vigorous fight against extradition at a hearing where the defendant was ordered to remain in jail at least until a bail hearing later this month.

Suspect Bruce Beresford-Redman did not enter a plea during his brief appearance in federal court in Los Angeles. Dressed in a T-shirt and blue jeans, the former "Survivor" producer politely answered questions from a magistrate judge about his identity.

He has been charged with aggravated homicide in Mexico in the death of his wife Monica while they were on a family vacation in April.

Beresford-Redman is due back in court on Nov. 29 for the bail hearing. His attorney, Richard Hirsch, said he will argue that the producer should be granted bail, since extradition proceedings could take up to a year.

"There are many discrepancies between their opinions and the physical evidence obtained in the case," Hirsch said.

Prosecutors want the judge to reject the request for bail. In a court filing, they the producer left Mexico after surrendering his passport and being told to remain there. Authorities also allege in a criminal complaint that there is evidence he killed his wife in a hotel room he shared with his young children.

"The callous disregard for her life and his children's safety and well-being, combined with his flouting of Mexican authorities' demands, demonstrates the ongoing danger posed by this fugitive," the document states.

Hirsch said he will file a reply to the government's motion next week, but there had been no obligation for Beresford-Redman to remain in Mexico.

"For me, there is no happy ending on this," said Jeane Burgos, the sister of Monica Beresford-Redman. "There is just a hope to get where we need to go for justice to be served."

Court documents unsealed Tuesday revealed the couple had argued in Mexico and blood had been found in their room.

Federal agents arrested Beresford-Redman Tuesday without incident at his home in Rancho Palos Verdes after a U.S. magistrate reviewed the documents that also said guests had told hotel security they heard "screams, crying for help and extremely loud banging from the room above."

A forensic expert later found traces of blood on sheets, a pillar and balcony railing of the hotel room the Beresford-Redmans were sharing with their young children, the documents state.

Attorney Hirsch said in a statement that he believed his client was innocent.

The 11-page complaint unsealed after the arrest described a contentious series of events before Monica Beresford-Redman's death.

The complaint states she discovered her husband was having an affair before the trip and had been seeking a divorce. Her sisters have said the couple traveled to Mexico in an attempt to reconcile.

The producer somehow was able to leave Mexico before authorities issued a warrant for his arrest in May. He has appeared in a Los Angeles courtroom several times to deal with custody issues related to his daughter and son, and on issues related to his wife's estate.

Last week, Bruce Beresford-Redman's parents were granted permanent guardianship of the couple's 5-year-old daughter and 3-year-old son.
