What to expect from opening statements

WBZ-TV legal analyst Jennifer Roman spoke about what can be expected from opening statements, which are set to be presented Monday morning.

"Both sides are going to lean into the very gruesome nature of this alleged crime. But they're going to take a very different approach," Roman said. "The prosecution is going to show signs that they think show premeditation, that she had been planning this and thinking about it and being methodical about it. The defense is going to throw the question, I think, back at the jury. How could somebody that's otherwise been known to be a loving and devoted mother, a caregiver, how could she have done this to her children unless she was suffering from a mental defect."
