Deliberations began Wednesday morning and by the afternoon, the jury returned with guilty verdicts on charges of first and second degree assault, reckless endangerment, and endangering the welfare of a child.
Smith was accused of assaulting the infant, with the child's mother testifying that she saw Smith hit the child with a closed fist three times.
Smith, who has served time in a similar case, will face up to 25 years in prison when sentenced September 12.
