Investigators said he later confessed that he was high, on PCP or angel dust according to witnesses, and grew violent. Police said that with Zaniyah still in his stepdaughter's hands, he stabbed her in the stomach.
A joint report released by two agencies in Sept. 2015, Waterbury police were called to the scene the day before the crime. Hapgood allegedly punched his wife in the face.
There was no arrest, however.
When police showed up for the baby's murder, Hapgood was said to be nude.
The family of the victim did not wish to speak following the sentencing.
