Executive says another man killed wife A Newport Coast man charged with killing his wife during a dispute told police that another man actually killed her and forced him to load the body into a truck and then drive his own vehicle toward to Mexican border, according to a source close to the investigation. Peter Gregory Chadwick, 48, pleaded not guilty Monday to a single count of murder for financial gain, He remains jailed on $1.5-million bail. Prosecutors say that Chadwick, a wealthy executive who lived in a $2.5-million home along the exclusive Newport Coast, killed his wife Wednesday as they fought over a possible divorce and related financial issues. Quee "Q.C." Chadwick, 46, vanished about the same time, authorities said. Her body has not been located. A source close to the investigation but not authorized to speak publicly said Chadwick offered a different story when he was taken into custody in San Diego, near the border. The businessman blamed the slaying on someone else and said he had been forced to load his wife's body into a truck and then drive south in his own champagne-colored Lexus SUV, the source said. But, the source said, Chadwick's story doesn't hold up because Newport Beach detectives have evidence that nobody else was seen in his car, and that even a CHP officer - who happened by chance to tail Chadwick's car at one point - said there was no passenger in his vehicle. The source said that detectives found signs of a bloody struggle in one of the home's bathrooms. The investigation has rattled the Newport Coast, a tony enclave of sprawling homes with spectacular ocean views that is home to celebrities like Kobe Bryant. Police went to the Chadwicks' $2.5-million home on Almanzora on Wednesday evening after a neighbor alerted authorities that no one had come to pick up the couple's children from school, Newport police spokeswoman Kathy Lowe said. When officers entered the five-bedroom home, they discovered "evidence of a struggle and possible foul play," she said.
