A man and a woman were arrested Wednesday in Atlanta on charges related to the death of their 2-month-old boy last year after investigators determined the child had ingested cocaine, police said.

Robert Williams, 41, and Makaylee Nevils, 24, were arrested without incident on one count each of second-degree cruelty to children and second-degree murder in the death of Robert Kingston Williams, Atlanta police said. They were booked into the Fulton County Jail and remain there without bond.

The boy was found unresponsive when officers were called to a home on Fairburn Place in northwest Atlanta on Sept. 20, police said.

According to an incident report obtained by The Atlanta Journal-Constitution, Nevils told police that she, Williams and their son went to sleep together around 9 a.m. Two and a half hours later, Williams and Nevils awoke to find their son face down in the bed. When they turned him over, they said they saw fluid coming from his nose and mouth and noticed he was not breathing, according to the report.

Grady emergency medical personnel were already at the home trying to resuscitate the child when police responded, according to the report. The boy was taken to Hughes Spalding Hospital but was pronounced dead in the ambulance before he arrived.

At the time, no charges were filed against Williams and Nevils.

Police said a homicide investigation was opened and coordinated with the Fulton County Medical Examiner’s Office. Investigators eventually determined that the boy had cocaine in his system when he died, according to police. No further explanation was provided for the gap in time between the boy’s death and the arrests of Williams and Nevils.
