Two-year-old Rodricus Williams died from blunt trauma to the head before his tiny body was placed in a trash can filled with 400 pounds of cement, says Glenn Rhoads, the Berkeley County coroner.

Rodricus’ father, Roger “Tony” Williams, is accused of refusing to get medical care for him after the boy’s health failed on June 7 in Summerville. Investigators have said that the boy’s father and his girlfriend Grace Trotman dumped the child in a cement-filled can behind an abandoned house in Bowman.

Arrests affidavits indicate that Rodricus died in early June while he was in Trotman’s care at her Longbourne Way home.

Authorities said the pair then concocted a story about the toddler falling into Charleston Harbor on July 6 while walking along The Battery sea wall. That led to an exhaustive, 12-hour search by police, fire and Coast Guard personnel that cost nearly $58,000 to conduct, according to city officials, before officials discovered the truth about Rodricus’ disappearance.
