Security officials say they suspect the two Palestinian terrorists who killed three and severely wounded several others in Elad last night arrived in the car of one of the victims.
The victim collected the two terrorists from an area near the security fence. Officials say the pair worked illegally in the city.
Once they arrived at the city, the two attacked and killed the man, before continuing their attack in the nearby park.
Officials did not yet specify which of the three victims had transported the terrorists.
According to Hebrew-language media reports, the victim knew the two and had transported them at least 10 times to the ultra-Orthodox city.
