House Speaker Robert DeLeo, D-Winthrop, said he has been briefed on the investigation into the death of a girl who came to be known as Baby Doe.
"They feel they have the perpetrators of this crime," DeLeo said during a news conference.
"It appears as though it was a situation of the boyfriend who was involved and apparently, I think, mother and boyfriend sort of blaming each other in terms of who harmed the child."
