10News learned the 103-year-old, 27-room Spreckels mansion was purchased by an unidentified group of investors at an undisclosed sale price.

Pharmaceuticals billionaire Jonah Shacknai bought the historic property on Ocean Boulevard in 2007 for $13 million, but its value was reassessed last year at $7 million.

In July, Shacknai's girlfriend, 32-year-old Rebecca Zahau, was found dead at the home -- a death San Diego County Sheriff's Department investigators later determined to be a suicide.

Two days before Zahau's death, Shacknai's six-year-old son, Max, was critically injured after falling down a grand staircase inside the home. Max died from his injuries several days later.

Zahau's family, however, disagreed with the sheriff's department's suicide conclusion, and last week, Rebecca Zahau's body was exhumed so famous forensic pathologist Dr. Cyril Wecht could perform another autopsy.

The results of Wecht's autopsy will be announced on a future episode of the "Dr. Phil Show."

A neighbor told 10News the sale of the mansion is good news, and noted that because an investment group now owns it, the home will be cared for until a buyer is found.

The neighbor said he has heard that the sale of the home by the investors will happen within the week.

The neighbor also told 10News the sale was important because it will begin the process of relegating a summer of tragic and widely publicized events to history.

Shacknai's realtor said his client has removed all of his personal property.
