Avi Dar will not stand trial for killing his landlady Tzipora Nahmo in August, but will instead be hospitalized in the Sha'ar Menashe psychiatric institution, the Jerusalem District Court ruled on Wednesday.
The 43-year-old M.A. student at Hebrew University rented an apartment from Nahmo on Rehov Meir Feinstein in Jerusalem's East Talpiot neighborhood. He stabbed his landlady to death with a nine-centimeter-long commando knife after slashing her in the face and body.
While the judges ruled that Dar committed the murder, they accepted his attorneys' argument that he could not be held responsible for his actions, and therefore was not fit to stand trial.
Dar will undergo an assessment every six months to determine whether he must remain within the psychiatric hospital.
The victim's son, Yinon Nahmo, told the judges that he wanted Dar to remain imprisoned for the rest of his life.
"I want the court to understand the crime that was committed here and the tragedy that we suffered. My mother was one of a kind, and this murderer, this monster, cut her life short, ruining all of our lives," Nahmo said.
"He deserves nothing less than suffering every single day of his life without seeing the sunshine. I demand that he be locked up for the rest of his life, if not in jail then in an institution," he concluded.
