Massachusetts officials have attended a memorial Mass near the Statehouse for a young girl whose body was found in a trash bag last month.

Wednesday's service at the Paulist Center was organized by House Speaker Robert DeLeo. His legislative district includes the Boston Harbor beach where the girl was found.

The Rev. Rick Walsh says the unidentified child is "our little girl." Gov. Charlie Baker says he wonders what her life was like before it ended "in such a terrible way."

State police have disseminated a composite image of the girl they call Baby Doe. She's white or Hispanic and about 4 years old, with long brown hair and brown eyes. She was found wearing black-and-white polka dot tights and had a zebra-printed blanket.

Authorities don't know how she died. They hope to learn more from DNA tests.
