Investigators say he was wearing a ring at the time he hit his girlfriend`s baby in the face, chest and head, causing eye damage, brain bleeding and swelling.
They hope to tie the ring to some of the baby’s injuries.
The baby`s mother, 20-year-old Brittany Whalen, has also been charged with child abuse and neglect.
Investigators say the two exchanged calls, texts and pictures detailing the baby`s injuries before their arrest.
Both are in the Hampton Roads regional jail on suicide watch.
