The Hampden County District Attorney says the eight month old girl on life support after allegedly being hit by her father has died in the hospital.
The father, Daniel Torres of Westfield is already being held on one million dollars bail on assault charges.
A police report suggests that Torres told officers that he struck the child in frustration.
There has been no word on whether charges will be upgraded in the case.
That decision could come later today.
