Thaddeus Maurice Calvary, a St. Andrews Middle School eighth-grader, died Monday after being found unconscious in a school bathroom, the boy's father said.
A report from the Charleston Police Department, which doesn't name Calvary because he is a juvenile, said EMS took the boy to Bon Secours St. Francis Hospital, where he was pronounced dead.
The boy's father, Thaddeus Calvary, confirmed that the child found in the school bathroom was his 15-year-old son.
His son, who lived with his paternal grandmother, had not been ill, the elder Calvary said.
Aurvella Calvary, the boy's stepmother, said her stepson is the child of her husband and Sonya Anderson. She also said her stepson appeared to be in good health and that he had played basketball Sunday.
Charleston County Deputy Coroner Kelly Myers said Monday evening that she had not yet determined the cause of death. An autopsy will be conducted today, she said.
St. Andrews Middle School was placed on temporary lockdown as a precaution after the boy was found, and police and extra district staff were at the scene, said Elliot Smalley, Charleston County School District deputy of strategic planning and communication. Extra counselors and support staff will be at the school for the remainder of the week to assist students and faculty, he said.
"Our deepest condolences go out to the family and to the St. Andrews Middle School community," Smalley said.
