District police are continuing to investigate the death of a 2-year-old boy who was found dead 10 days ago in his home near the Potomac Avenue SE Metro stop, police said.

About 6:45 a.m. July 10, police responded to a call about an unconscious person and found Julio Guy Thomas in a house in the 700 block of Kentucky Avenue SE, police said.

Julio was lying unresponsive on a bedroom floor, police said. He was taken to D.C. General Hospital, where he was pronounced dead at 7:25 a.m.

Three other children in the household were taken and placed in the care of the child and family services division of the city's Human Services Department, police Lt. Keith L. Williams said yesterday.

The D.C. medical examiner's office said it had determined that the cause of death was homicide. Julio suffered blunt force trauma to his torso and head, causing brain swelling, Jonathan L. Arden, the city's chief medical examiner, said yesterday. The child also had a subdural hemorrhage at the base of his skull, rib fractures and lacerations to his liver and spleen, Arden said.

Julio's family could not be reached for comment.

A neighbor said the family had lived in the two-story brick house for about a year.

Another neighbor, who works with the Orange Hat Patrol on the block, said yesterday that she was awakened by the ambulance early in the morning of July 10.

The neighbor, who did not want to be identified, said she soon began to collect donations to assist with the funeral and asked neighbors to help her locate the boy's parents, whom she did not know.

The neighbor said residents on the block were "shocked to no end" when word spread that the cause of death had been ruled to be homicide.

"I have lived around here pretty close to 50 years, and to my knowledge I have never, ever heard of anything like this happening in our neighborhood," the neighbor said.
