Man Chewed Off Elderly Person's Ear Thinking He Was A 'Robot Trying To Kill Him'

An Oregon man accused of chewing off an elderly man's ear said he thought the victim was a "robot trying to kill him," an arrest affidavit revealed.

The 25-year-old suspect, Koryn Daniel Kraemer, was charged with second-degree assault for attacking the 70-year-old unidentified man on a light-rail train platform near Portland, ABC News reported. Kraemer appeared in court Wednesday.

Deputies reached the platform in Gresham after receiving a report of an attacker on top of a man who was covered in blood Tuesday, according to the probable cause affidavit.

An officer forcibly removed Kraemer from the victim and rushed the latter to a hospital. The elderly man's right ear was bitten off. He is reportedly in stable condition now.

The injury was so severe that responders could see part of his skull after the attack, the affidavit said, reported Hawaii News Now.

The suspect was initially booked under the name "El Baker" based on the only detail he provided them while he was taken into custody. Officers later identified him using his fingerprints. Kraemer had recently moved to Portland from Georgia, officials said.

During interrogation, he told cops that he consumed alcohol, marijuana and fentanyl pills before the attack. Kraemer claimed he thought the victim was a robot based on his smell and that he spit the flesh onto the ground during the attack.

Kraemer is being held in custody without bail. He entered a not-guilty plea to the charge.

In an unrelated incident, an "unruly" patient at a Florida hospital was arrested last year after he initiated a fight with a security guard and bit off another guard's finger. The 19-year-old patient, identified as Dillon Metoyer, started acting erratically while he was being treated by a nurse at the Lee Memorial Hospital in Fort Myers. While the guards attempted to restrain Metoyer, he head-butted one of them and bit off part of the second security guard's middle finger. The teen was charged with battery (touch or strike) and felony battery.
