According to the Telegraph, Israeli authorities have now informed the British embassy that Julie died of natural causes. Police consider the case to be closed.
But Deborah Pearson said she felt “something was not quite right” about the cause of death.
"Julie never complained of a stomach condition that I know of. It sounds strange,” she said.
She added that the family would wait until they had seen the pathologist’s full report before considering what action to take, including whether to lodge a complaint against Israeli police.
Julie Pearson moved to Israel in 2014 and had applied for citizenship. Her father was Jewish.
