Shlomi Mark, the 29-year-old eldest son of a rabbi killed in a terror attack almost three years ago, was killed in a fatal traffic accident on Friday, plunging his family into another round of tragedy.

Mark was on his way to work at the Prime Minister’s Office in Jerusalem when his motorbike crashed. He was evacuated to Soroka Medical Center in Beersheva, where medical staff fought to save his life, but he was pronounced dead on Sunday morning.

Mark’s father, Rabbi Miki Mark, served as the director of the Otniel yeshivah in Judea and was driving from his home in Otniel to Hebron on July 1, 2016 with his family when an Arab terrorist drove up alongside the vehicle and shot the rabbi, causing the car to crash. The rabbi, a father of 10 children, he was killed instantly; his wife, Chava, sustained a serious head injury.

The first people to arrive at the scene were local Arabs, who provided the attack survivors with a cellphone to call for help, and stayed with them until medical and security personnel arrived.

Since the murder, Shlomi Mark took upon himself the task of providing for his siblings.

Mark is survived by his family, as well as his wife, Yiska, and their three children.

Yiska Mark is the daughter of Eliyahu Ben-Ami, who was murdered in a terrorist attack in 2000, when a car of gunmen sprayed his vehicle with gunfire as he drove a group of teachers to work at a school in Kiryat Arba, adjoining Hebron.

Shlomi’s funeral was set for Monday.

“Simply inconceivable the pain that has befallen this family,” Education Minister Naftali Bennett said on Twitter. “That nation of Israel stands at your side in your dark time. May you know no more pain.”

“We are shocked and saddened in the face of the terrible tragedy,” said Yochai Damri, head of the Har Hevron Regional Council and a family friend. “Shlomi, from the time he joined the army to this day, chose to devote his best years to the security of the State of Israel as an officer and later in the security establishment. Our heart is broken.”
