Jamarius Ruffin said he was sleeping with his son when he woke up and found he wasn’t breathing. But the Jefferson County Coroner’s Office determined the cause of death and found older injuries during the examination.

The Jefferson County Sheriff’s Office obtained a capital murder warrant for the father’s arrest, and he was taken into custody on Friday by the U.S. Marshals Gulf Coast Regional Fugitive Task Force, according to AL.com.

Ruffin is being held at the Jefferson County jail without bond.
