Little Cameron Hoopingarner, who was also blind, was discovered by police after they received an emergency call about a child in cardiac arrest in Indianapolis, reports The Sun.

The boy was rushed to Union Hospital but was later pronounced dead on Tuesday.

Pathologist Dr Roland Kohr described Cameron’s case as “one of the most disturbing autopsies I’ve ever done”.

Dr Roland Kohr said the autopsy was one of the worst he done in his career.

He told WTHITV: “This child is so severely malnourished that the closest thing I can think of are the pictures from World War II concentration camps. There were bodies which were stacked like wood, literally skin and bones. This child looked like that.”

At a press conference on Wednesday, Sheriff Greg Ewing said: “His cause of death was severe malnutrition, and the manner was homicide as ruled preliminary by the coroner’s office.

“Essentially in my opinion, he was starved to death.”

Four people have been arrested in connection with the young boy’s death including Cameron’s two guardians, Robin Lee Kraemer, 53, and Hubert Kraemer, 56.

Two other occupants of the home, Sarah Beth Travioli, 30, and Chad Kraemer, 33, were also arrested.
