LOWELL, Mass. (AP) -- A Lowell man has been indicted on a second-degree murder charge in connection with the death of his 9-week-old son.

The Sun ( ) reports that a grand jury on Thursday indicted 22-year-old Christopher Berry in connection with the death in May of William Berry.

Prosecutors say the baby was taken to a hospital on May 11 suffering from "catastrophic brain injuries" authorities say were caused by violent shaking. The little boy died at a Boston hospital about a week later.

Berry has been held on $500,000 bail after pleading not guilty in May to assault and battery on a child causing substantial bodily injury.

Berry’s attorney has said his client has post-traumatic stress disorder after serving a year in Afghanistan and has been receiving medication and counseling.
