A federal judge in Los Angeles upheld the extradition back to Mexico for Bruce Beresford-Redman on Wednesday -- the Survivor producer accused of killing his wife in Cancun in April 2010 -- to face charges of aggravated homicide.

Mexican authorities provided "pages upon pages of competent evidence demonstrating that [Beresford-Redman] committed the offense for which extradition was sought, namely the aggravated homicide of the victim," U.S. District Judge Philip S. Gutierrez said in a two-page ruling.

Gutierrez cited "the infidelity, fighting, screaming from the hotel room, the fugitive's opportunity to dispose of the victim's body" as credible pieces of evidence to merit the extradition of the Emmy-nominated producer.

The late Monica Beresford-Redman's sisters, Carla and Jeane Burgos, told The Today Show Wednesday that they're satisfied with the job Mexican authorities are doing in trying to extradite their former brother-in-law Bruce Beresford-Redman in connection with their sister’s death in Cancun last year. 

Mexican authorities alleged in new extradition papers filed in Los Angeles, that Bruce Beresford-Redman had premeditated wife's killing, hitting in her head with a blunt object before fatally choking her.

New court documents obtained by RadarOnline.com claim former Survivor producer Bruce Beresford-Redman spent $5,000 on a daylong phone-sex chat and had an affair with a woman he worked with and at one point — a story we first told you about.

Mexican authorities are attempting to extradite Beresford-Redman, 38, who is accused of murdering wife Monica, whose body was found April 8, last year, in a sewer at the Moon Palace Hotel resort in Cancun. Investigators have said her body showed signs of asphyxiation and evidence of a heavy blow to the right temple.

Bruce Beresford-Redman, the Survivor producer accused of murdering his wife, is due in a Los Angeles courtroom Tuesday for a hearing in which his lawyers will argue he's being held unconstitutionally, as prosecutors in the case haven’t shown enough evidence to keep him in custody.

Prosecutors counter it's too early in the case to present the evidence against Beresford-Redman, RadarOnline.com has learned.
