U.S. producer Bruce Beresford-Redman was expected to be arrested as a suspect in his wife's strangulation death, officials told ABC's "Good Morning America."
Her husband had reported her missing four days earlier.
The couple had been on vacation in the resort area with their two children at the time of her death.
Unidentified Mexican authorities involved in the case told "Good Morning America" hotel guests complained of hearing the couple fighting before the woman disappeared.
Investigators said they found inconsistencies in the 38-year-old television producer's account of what happened and expected to arrest him Monday, a report from "Good Morning America" said."GMA" said Beresford-Redman already has met with the high-profile Mexican attorney who successfully defended Duane Chapman of the "Dog, the Bounty Hunter" show when he was accused of illegally arresting a convicted rapist.
Beresford-Redman's TV credits include "Survivor" and "Pimp My Ride."
