UPDATE: Husband Accused of Killing His Missing Newport Wife

A Newport Beach man was arrested early Thursday on suspicion of killing his missing wife.

Peter Gregory Chadwick, 48, was being held on suspicion of homicide, and investigators are asking for the public’s help finding his 46-year-old wife, Quee "Q.C." Chadwick.

According to police, on Wednesday at about 7 p.m., officers responded to a home on Almanzora in Newport Coast to check on the welfare of the residents after they neglected pick up their children from school.

"A neighbor became concerned for the children of her neighbors when she discovered they had not been picked up from school earlier that afternoon," Newport police spokeswoman Kathy Lowe said. "Officers responded to the home and observed evidence of a struggle and possible foul play."

The next morning at 5:30 a.m., Peter Gregory Chadwick, 48, was taken into custody in San Diego after he called police there for help. Police declined to release details about why Chadwick called for help.

Neighbor Yulianna Nikulina told the Daily Pilot she heard Quee Chadwick scream earlier in the week. She said she never heard any arguing coming from the Chadwick home.

"I can only tell you good things about this couple," Yulianna told the newspaper.

The Newport Beach Police Department is currently conducting a thorough search of the areas believed to have been traveled by Peter Chadwick during the approximately 12 hours prior to his contact with the San Diego Police Department.

At the time Chadwick was contacted by San Diego police, he was driving a champagne-colored 2003 Lexus SUV.

Peter Chadwick was transferred from Newport Beach jail to the Orange County jail on Sunday, and is being held on $1.5 million bail.

Anyone who may have information regarding this crime is asked to contact the Newport Beach Police Department at 800-550-NBPD or Detective Bryan Moore at 949-644-3764. Messages can be left anonymously if desired.
