UPDATE: On April 14, McKay was charged with first-degree murder. He is being held in the Charles County Detention Center with no bond.

Man Charged in Connection with Physical Child Abuse: On March 30 at 2 a.m., officers responded to the 2000 block of St. Thomas Drive in Waldorf after a man called and reported his 13-month old daughter was having trouble breathing. When officers and paramedics arrived, the child was unresponsive. She was transported to a hospital and then flown to Children’s National Medical Center in Washington, D.C. Upon examination and other medical testing, detectives learned the toddler sustained trauma consistent with child abuse. She was in critical condition. Detectives subsequently arrested the toddler’s father, Robert Earl McKay, III, 29, of Waldorf, and charged him with child abuse, first-degree assault, and second-degree assault. The child’s mother was at work when the 911 call came in. Further, no other children reside at the residence.

On March 31, the victim, Divinity Ose McKay, was pronounced deceased. Since then, detectives worked with the Charles County State’s Attorney’s Office and on April 14, McKay – who was still being held in the Charles County Detention Center – was charged with first-degree murder. Anyone with additional information is asked to call Detective A. Worley at (301) 609- 6518. The investigation is ongoing.
