The boy's stepfather, Markiece Palmer, 34, and the boy's mother, Dina Palmer, 27, were arrested and charged with murder, child abuse and neglect in the beating death of Roderick Arrington, a second-grader at Roundy Elementary School. A hearing on the murder charges is scheduled for 7:30 a.m. Thursday in Las Vegas Township Justice Court.

On Thursday, Arrington was transported to University Medical Center because he was unresponsive, according to an arrest report released Monday. The arrest report said officers were called to the hospital after medical officials observed severe bruising and massive brain swelling, but a news release issued Tuesday said officers were called at 8:45 a.m. Thursday to a residence in the 3100 block of South Decatur Boulevard to check on an unresponsive 7-year-old with significant injuries.

Arrington was admitted to the UMC's pediatric intensive care unit in critical condition. A doctor reported that Arrington suffered from strokes and fixed pupils and had bruises on the arms, abdomen, back, legs, thighs and buttocks.

"The buttocks had fresh open wounds that appeared to be from being whipped," the report said, adding that some of the bruises had left some tissue dead.
