California man accused in deaths of family of 4 on trial

For years, the disappearance of the McStay family from their San Diego County home puzzled investigators, with no signs of forced entry and the couple's credit cards untouched.

After their remains were found years later in a remote desert location more than 100 miles away, authorities charged a Southern California man with the killings, alleging he bludgeoned his business partner, partner's wife and two young sons with a sledgehammer before burying them.

Now, 61-year-old Charles "Chase" Merritt is facing trial in the murder of Joseph McStay, McStay's wife Summer, and their 3- and 4-year-old boys. Opening statements are expected today in San Bernardino County, where the family's remains were found.

Merritt, who was a business associate of McStay, has pleaded not guilty. Merritt could face the death penalty if convicted.
