"A very close friend" of a woman killed at a Cancun, Mexico, resort sold e-mails purportedly exchanged between the dead woman, her husband and his alleged mistress to a gossip website, the website said.
The e-mails were published by Radaronline.com on Thursday, a day after Ely Burgos, Monica Beresford-Redman's mother, gave copies of e-mails to Mexican authorities investigating her death.
A lawyer for the dead woman's family said the e-mails did not come from them and she pleaded with "the person who has obtained them to stop leaking information to the media that may be critical to the pursuit of justice."
"We have been aware of their existence for some time now and have shared them with the proper authorities," attorney Alison Triessl said. "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."
Reality TV producer Bruce Beresford-Redman was detained as a suspect on April 8, soon after his wife's body was found in a sewer near their Cancun hotel. He was released a day later while police gathered more evidence.
