A Massachusetts woman convicted of beating her 11-month-old niece to death more than five years ago while she was caring for the girl was sentenced Thursday to up to 7 years in prison.

The sentencing of Shu Feng Hsu, 32, of Quincy, came several days after she was convicted of manslaughter in the death of the baby, who was taken to the hospital in February 2018 with blunt force head and brain injuries consistent with a 40 mph vehicle crash, prosecutors said. She died days later.
