'Survivor' Producer Still 'Person of Interest'

The former 'Survivor' producer who is again ensconced in L.A. is still "a person of interest" in his wife's murder ... Mexican law enforcement sources tell TMZ.

An official involved in the investigation of Monica Burgos Beresford-Redman tells TMZ, "Of course he is still a person of interest to officials in this case."

TMZ broke the story that Bruce Beresford-Redman came back to L.A. -- but it is unclear if he came back with a passport.

Mexican authorities had previously told Beresford-Redman not to leave the country pending the investigation -- it is unclear if he obtained permission before leaving.
