An investigation into Friday's attack outside Ariel revealed that the father of one of the gunmen was aware of their actions and aided and abetted them.
After carrying out the shooting that claimed the life of 23-year-old Vyacheslav Golev, the two fled in a car which they torched using a flammable substance they had brought with them in advance as part of the planning of the attack.
The father of one of the terrorists picked them up in his car from the site of the burning vehicle.
In addition, the father was the one to point Israeli forces to where the two Carl Gustav submachine guns used in the attack were stashed.
