Yosef Haim Ben David was convicted on April 19 for the July 2014 murder of a Palestinian teenager.
Ben David, 30, the main suspect of the crime, was convicted by a district court in Jerusalem, after rejecting his insanity plea claiming he was not responsible for his actions.
“The court has found that at the time he committed the offense, the accused was not psychotic, fully understood the facts, was responsible for his actions, had no difficulty in understanding reality and had the capacity to prevent the crime,” said the Justice Ministry, according to the Times of Israel.
Ben David will be sentenced next month and may face up to life in prison for the murder of 16-year-old Mohammed Abu Khdeir, which was a revenge for the death of three kidnapped Israeli teens earlier that summer.
Two other Israelis have already been sentenced for their involvement in the murder of Kheider.
The Israelis caught Khdeir from a neighborhood in East Jerusalem. They took him to a forest in Jerusalem and burned him to death.
“Every time I see the faces of those who burned my son, I can’t sleep at night. Such a person should not be shown any leniency, he should get a life sentence,” said the father of the victim, Hussein Abu Khdeir.
The brutal murder of Khdeir sparked riots and tension between Israelis and Palestinians. The events sparked the Gaza war later that summer.
