“I’m shocked. I can’t understand how this could happen to a 3½ -month-old baby. I just don’t believe it,” he said.

On Sunday morning, Walter went to work at a Wendy’s, and Gazzam and his daughter took a nap in bed.

Investigators said that when questioned, Gazzam originally said that his daughter was likely injured when she fell out of bed. Later, he said his daughter was fussy and she would not stop crying when he changed her diaper.

According to the criminal complaint, Gazzam then admitted he repeatedly punched his daughter with a closed fist while she was lying in bed.

When police and paramedics arrived at the home just after noon on Sunday, the child was unresponsive. When she arrived at St. Clair Hospital, a doctor said she had bruises on her body and her left arm was broken.

“You see this and hear this. I’m still at a loss of words; I’m just totally shocked still,” Paree said.

Gazzam was arrested and charged with homicide, recklessly endangering another person and endangering the welfare of a child.
