An investigation has found that three-year-old Adelle Biton’s wounds were caused directly by a rock flung at her car, Channel 10 reports.

Adelle, her mother and two sisters were all wounded several weeks ago when terrorists hurled heavy stones at their car as they drove in Samaria (Shomron).

The rock attack caused a car crash, and it was initially believed that Adelle’s injuries, along with those of her mother and sisters, were a result of the crash.

However, the investigation showed that Adelle was hit in the head by a stone the size of an adult man’s fist. The resulting head injury left Adelle in critical condition, and she has been comatose for the past six weeks.

Adelle was two years old at the time of the attack. Last Thursday her family celebrated her third birthday at her bedside.

One month ago it was reported that police and soldiers had arrested five Palestinian Authority teenagers, ages 16-17, who are suspected of having stoned the Biton family’s car. The five have confessed to the attack.
