(Des Moines, Iowa) -- A Des Moines man is facing multiple charges in the death of his four month-old daughter.
A criminal complaint filed in court says Zackary Wallace's daughter had a serious head injury while Wallace was the only one watching her.
The complaint says doctors confirmed she could not have inflicted the injuries on herself.
Investigators say Wallace was unable to provide a reasonable explanation of how his daughter got the fatal injuries.
Wallace is being held without bail until his initial court appearance.
