WINSTON-SALEM, N.C. (AP) — A 19-year-old North Carolina man has been charged with murder and child abuse in the death of his 7-month-old son, police confirmed Wednesday.

Christion Vaughn Jones was arrested and booked into jail without bond, Winston-Salem police said.

Authorities initially responded to an apartment on the morning of July 4 and found family members performing CPR on the unresponsive boy, police said.

The child was pronounced dead at a hospital and autopsy results showed he suffered a torn liver, broken ribs and a damaged intestine, among other internal injuries, according to an arrest warrant obtained by the Winston-Salem Journal.

Authorities did not comment further on the circumstances.

Jones was set to appear in court April 30, news outlets reported. It’s unclear whether he had an attorney who could comment on his behalf.
