Emile Buskila, arrested on Monday on suspicion of stabbing his father to death in Rehovot, has been sent for psychiatric evaluation by the Ramle Magistrate's Court on Wednesday.
The 27-year-old man's custody was also extended by a week.
Police launched a large scale search on Monday after Buskila fled the crime scene in his home, and captured him after a few hours hiding in an abandoned building near a cemetery.
