The suspect in the senseless slaying of a Chase employee stabbed inside one of the bank's Chicago branches had previously been charged with attacking two other women in 2014 but found not guilty by reason of insanity, police officials said.
Jessica Vilaythong, 24, was talking to a fellow employee inside the bank when a man entered the building and spoke briefly with Vilaythong before stabbing her in the neck on Wednesday.
Vilaythong died from her injuries on Thursday, and Chicago officers apprehended a 35-year-old man who had been arrested for assaulting and robbing two 55-year-old women in Navy Pier in 2014.
The man had been found not guilty by reason of insanity and had been released into a mental health center in 2017, NBC 5 reports.
Police have not identified the suspect and said the investigation was still ongoing.
Witnesses said they saw the man brandish the bloody knife on the street following the attack, covered in blood.
