According to the arrest affidavit, Mahlab called 911 on Saturday, Jan 28th to report his son was unconscious.

The child was transported to Jackson Memorial Hospital where X-rays showed the infant had a fractured skull, subdural bleeding, retinal hemorrhage and bleeding on the brain.

The affidavit said the father admitted to hitting his son “with force in the face twice.” After the child was hit a second time, he fell off the father’s lap and hit his head on a nightstand.
