Seventeen-year-old Walid Ahmad, who had been held for six months without being charged, suffered from extreme malnutrition, and also showed signs of inflammation of the colon and scabies, said a report written by Dr. Daniel Solomon, who watched the autopsy, conducted by Israeli experts, at the request of the boy’s family.

The Associated Press obtained a copy of Solomon’s report from the family. It did not conclude a cause of death, but said Ahmad was in a state of extreme weight loss and muscle wasting. It also noted that Ahmad had complained to the prison of inadequate food since at least December, citing reports from the prison medical clinic.

Ahmad died last month after collapsing in Megiddo Prison and striking his head, Palestinian officials said, citing eyewitness accounts from other prisoners. Israel’s prison service said a team was appointed to investigate Ahmad’s death and its findings would be sent to the authorized authorities.

Ahmad is the youngest Palestinian prisoner to die in an Israeli prison since the start of the Gaza war, according to Physicians for Human Rights Israel, which has documented Palestinian prisoner deaths. He was taken into custody from his home in the occupied West Bank during a pre-dawn raid in September for allegedly throwing stones at soldiers, his family said.

The autopsy was conducted on March 27 at Israel’s Abu Kabir Forensic Institute, which has not released a report of its findings and did not respond to requests for comment. The Ahmad family’s lawyer, Nadia Daqqa, confirmed Solomon, a gastrointestinal surgeon, was granted permission to observe the autopsy by an Israeli civil court, AP reported.

Malnourished and frail

According to Dr. Solomon’s report the autopsy showed that Ahmed likely suffered from inflammation of the large intestine, a condition known as colitis that can cause frequent diarrhea and can in some cases contribute to death.

But medical experts said colitis usually doesn’t cause death in young patients and was likely exacerbated by severe malnutrition.

“He suffered from starvation that led to severe malnutrition and in combination with untreated colitis that caused dehydration and electrolyte levels disturbances in his blood which can cause heart rate abnormalities and death,” said Dr. Lina Qasem Hassan, the head of the board for Physicians for Human Rights Israel who reviewed the report at the request of the AP.

She said the findings indicated medical neglect, exacerbated by Ahmad’s inability to fight disease or infection because of how malnourished and frail he was.

Dr. Arne Stray-Pedersen, a professor of forensic medicine at the University of Oslo in Norway who was not involved in the autopsy, said the report suggests there was a period of prolonged malnutrition and sickness lasting at least a few weeks or months. “Based on the report, I interpret the underlying cause of death to be emaciation-wasting,” he said.

Scabies rashes were also noted on his legs and genital area, the report said. There was also air between his lungs that expanded into his neck and back, it said, which can cause infection. Air can come from small tears in the lungs, which can occur from severe vomiting or coughing, it said.

Ahmad’s family said he was a healthy high schooler who enjoyed playing soccer before he was taken into custody. His father, Khalid Ahmad, said his son sat through four brief court hearings by videoconference, and he noticed at one of them, in February, that his son appeared to be in poor health.

The family hasn’t yet received a death certificate from Israel, the elder Ahmad said Friday, and are hoping Dr. Solomon’s report will help bring his son’s body home.

“We will demand our son’s body for burial,” he said “What is happening in Israeli prisons is a real tragedy, as there is no value for life.”
