A man who admitted to brutally killing and chopping up the body of his mother four years ago was sane at the time of the murder, a San Diego County jury found Thursday.
The remains of Sherry Chu Chang, 60, were found in her Solana Beach home in January 2010.
Homicide investigators discovered one of the victims' arms in the refrigerator and a piece of her skull in a drawer in the home on Santa Florencia. Her body had 75 wounds delivered by a hammer, officials said.
When her son, Bryan Chang, was arrested at his home in Los Angeles two days after the killing, investigators say he still had blood in his ear and under his fingernails and toenails.
Chang, now 33, pleaded guilty last month to first-degree murder however his defense argued Chang was insane at the time of the crime.
On Thursday, the jury determined he was sane.
Just weeks before her death, Sherry Chang had put her unemployed son on a prayer list at a nearby church. She had ended her financial support of her son before her death, prosecutors said.
