Police stress that, despite his arrest, there is “no definitive proof” linking Dadovich to the crimes. A number of objects from his apartment were seized and are now being checked by the police lab.
The suspect denies any connection to the stabbings and the murder, and is maintaining his right to remain silent.
Khairi Alkam, 51, from Jerusalem’s A-Tur neighborhood, was the single fatality in the six knifings. The father of nine was attacked on May 13. The other stabbings occurred on February 17, March 10, March 12, April 29, and May 7.
In five of the stabbings, the attacker left his knife at the scene.
Police at first suspected criminal motives, without a nationalist impetus. But later, they found materials at the scene of attacks that indicated the assailant was targeting Arabs, Jerusalem police spokesman Shmuel Ben-Ruby said.
He said police believe the stabbings were intended as acts of revenge, after Jews were killed by Arabs in Jerusalem.
