April 23, 2010 -- The recently revealed e-mails between former "Survivor" producer Bruce Beresford-Redman and his now-slain wife suggest not only his affair but a marriage mired in lies and frustration.
It was a private argument between husband and wife that has now become very public. Bruce Beresford-Redman is considered the only suspect in his wife's death. Mexican authorities have yet to charge anyone but have ordered the Hollywood producer to remain in the country.
The e-mails, obtained by RadarOnline, were discovered on Monica Beresford-Redman's home computer. Her family brought them down to Mexico to give to authorities as evidence of a possible motive.

"She has gone even further than I thought she would," Bruce Beresford-Redman wrote to his alleged mistress, Joy Pierce. "She has denied me access to my children. ... She has shut me out of my home, she has liquidated all my money and ... she has alleged at my daughters school that I am abusive and unfit."
They were reportedly sold to RadarOnline by a family friend, a move that upset her family.
"The Burgos family did not sell or authorize the release of any e-mails to the media," family lawyer Alison Triessel said in a statement.
"Given their sensitive nature, we asked the authorities that they be preserved and kept confidential, as we believe they are relevant to this ongoing investigation," she said. "We plead with the person who has obtained them to stop leaking information to the media that may be critical to the pursuit of justice for Monica Burgos."
Family: Couple's Relationship Troubles Well-Known
Even Monica Beresford-Redman was corresponding with her husband's mistress, according to the e-mails, telling her that she had recorded him in the car and calling him a "liar" and "my embarrassing husband."
"I just want to expose him, so he can feel stupid," she wrote to Pierce. "That will help me? Probably not, but he has to grow up one day."
Neighbor Lori Wheeler said she never saw the couple fight, but close friends and family now say they knew otherwise.
"They had a rocky relationship and I think that was fairly well known," Triessel said.
In an e-mail to Monica Beresford-Redman, Pierce apologized for the affair and offered to help her however possible.
"I apologize for my involvement in the situation, but please know I was acting out of what I believed was pure love between the two of us," Pierce wrote.
But in a subsequent e-mail, Pierce tried to cut off contact, telling Monica Beresford-Redman, "I am no longer involved in your situation and would like to be left alone. Best of luck."
Family therapist Terry Real said the situation was heartbreaking.
"This is about the worst possible thing that could happen," said Real, who has no connection to the case. "Once you cross the line into infidelity, it's a very volatile situation."
The trip to a posh Cancun resort with their two small children was reportedly taken to repair their marriage. Instead, Monica Beresford-Redman was reported missing. Her body was found days later. Mexican authorities said she had been strangled and hit hard in the head.
Hollywood Producer Suspected in Wife's Death From the Start
Mexican authorities have said from the beginning that Bruce Beresford-Redman's account of his wife's activities before she disappeared in the days before her body was found don't match witness testimony.
"Everything that we have seen certainly points to Bruce as ... the only suspect," said Former Los Angeles County prosecutor Robin Sax, who has no connection to the case. "I think there's no one else for them to look at."=
Shortly after his wife's body was recovered, Beresford-Redman requested she be cremated, according to Mexican authorities who say their investigation is nearly complete.
It was a revelation the family found "disturbing," according to a lawyer.
Beresford-Redman's sister told "Good Morning America" this week that the idea that her brother-in-law might have been capable of such a horrific crime saddens her.
"I think everybody can be capable of murder. And I'm really sad if he did," Carla Burgos said. "She was a very, very pleasant person."
An arrest in the case has been delayed, pending forensic testing, but Monica Beresford-Redman's family said it wants justice immediately.
"We want the person that murdered my sister," Jeane Burgos said. "I want this person in jail to pay for the rest of his life for what he did."
Burgos said she doesn't believe Beresford-Redman's story that his wife disappeared after she left by herself to go shopping.
Police officials said there is no record of her having left the hotel grounds.
Security guards check all cars that come and go.
"It's just like horrible, it's just like so hurtful," Jeane Burgos said. "I can't even express how much pain is inside my body."
The couple's two children are back in Los Angeles. A judge has granted temporary custody to their father's parents, but their maternal grandparents are fighting for custody.
