Three Israeli Arabs have been arrested in connection with the murder of Katy David, a security guard whose body was found in a grove of trees not far from the police station in Hadera on Sunday. The suspects are all residents of Baka al-Gharbiya. One of them, who was reported to have had relations with the 27 year-old woman, surrendered himself to the police on Tuesday through the auspices of his lawyer. Another resident of Baka al-Gharbiya was subsequently arrested in connection with the murder. The third suspect, also a resident of the same village, is believed to have tried to cover up evidence. Ch.-Supt. Moshe Weizman, spokesman for the Coastal District, said that police were investigating two possible motives in connection with the murder - criminal or nationalistic. "We have certainly not ruled out the nationalistic motive, despite the fact that one of the suspects surrendered himself," Weizman told Jerusalem Post on Tuesday night. According to details of the inquiry, the woman security guard worked as a "selector" at a night clubs and was not armed. No weapon was found on her body at the scene of the murder and police said it appeared that she had not been armed. It is believed that she was brought to the scene because of her connection with one of the suspects, although it is still not clear if this was done by force or persuasion.
