I'm not so sure Michael McCarthy isn't talking. Maybe he is cooperating with the prosecution:
'Baby Doe's' Mother Could be Hit With More Charges
At this stage in the investigation, more charges could be filed against Bond, Conley told the Boston Herald. “We don’t foreclose that possibility,” he said.
Statements made by Bond to investigators revealed McCarthy allegedly punched Bella to death because she had been acting “unruly."
According to Conley, Bella’s exact cause of death is still a mystery, but suffocation and asphyxiation is being looked at as a possible cause.
Other people could be charged in connection to Bella’s death, but Conley said that it is not a definite at this time.

I think Bella's little body is telling a different story than being punched in the stomach which inconsistent with Rachelle Bond's story.
DA: Baby Bella’s mom could face additional charges
Suffolk County District Attorney Daniel F. Conley said his office isn’t ruling out additional charges against the mother of baby Bella Bond, whose cause of death still remains a mystery to investigators.
But Conley said the door is still open to more charges against Bond, who authorities say admitted to a friend that McCarthy killed her daughter and that she was an “accessory after the fact.”
“We don’t foreclose that possibility,” Conley said.
He also said that as the investigation continues, others could be charged if necessary, but he gave no indication that was likely.
The state medical examiner’s office has yet to rule on a cause of death for baby Bella, a fact that Conley said remains “perplexing.”
Conley said authorities still don’t have a timeline for a cause of death from the medical examiner, but the office has previously said that natural causes and disease were not being considered and
suffocation or asphyxiation had not been ruled out.
“I know they’re working on it hard, hoping for the best to come up with answer as soon as possible for the family and for
all of us who would like to know the reason why Bella passed,” he said.
