Michael Burell was arrested for injuring his 7-month-old son. Police were called to the home last week because the child was not breathing.
The child's mom says she was at school when her son was injured. Her husband told her the child fell and hit his head on a toy.
Doctors at Children's Hospital Central California later determined the infant's injuries did not appear accidental and more in line with shaken baby syndrome.
The baby was declared brain-dead over the weekend.
