An infant whose father will stand trial for murder in the toddler’s death had injuries consistent with being shaken to death, a deputy state medical examiner said during a hearing Thursday.

Jamaro South Jr., 6-months old, and brain and eye injuries that typically only occur because of “extreme force” trauma such as shaking or a car crash, Deputy Chief State Medical Examiner Dr. John Brentley Davis said.

The boy’s skull showed two points of impact, and he had detached retinas and bruising in his brain and on several organs, Davis said.

“It was a significant amount of force. These aren’t injuries you get from simply being dropped or from CPR,” Davis said during a probation revocation hearing for Jamaro South Sr., whose address was not available.

South will stand trial for first-degree murder Sept. 2. Police have said he shook the toddler to death as he was watching the boy in December. The 6-month-old died Dec. 15 at University of Mississippi Medical Center in Jackson.

Davis performed the autopsy and determined the toddler died as a result of homicide.

“These were inflicted injuries, not accidental trauma in a child this age,” Davis said.

Defense attorney Chris Green questioned if Jamaro could have suffered the injuries before he was in his father’s care.

“He would have rapidly lost consciousness soon after the injuries were sustained,” Davis said.

Davis’ testimony was part of a hearing to determine if South will go to prison for violating a nonadjuticated court sentence for embezzlement. Being arrested for a crime is considered a probation violation under state law.

Circuit Judge M. James Chaney recessed the hearing until 10 a.m. Tuesday.
