The Newport Coast resident is accused of killing his wife, Quee, in October 2012 and then dumping her body in San Diego County. He was arrested on Oct. 11 near the U.S.-Mexico border.

Chadwick, a real estate investor, and his wife were discussing the possibility of divorce at the time of her murder, officials said. Following his arrest, investigators found blood and signs of a struggle inside the couples’ upscale home.

Police were alerted to Quee’s disappearance after she failed to pick her three children up from school.
