Upon their arrival, police said officers found the suspect, Koryn Kraemer, 25, still on top of the victim, attacking him.
The victim reportedly suffered severe injuries to his head and face. Police said they discovered the victim had not been stabbed, but the suspect had chewed off his ear and part of his face. The victim’s skull was allegedly exposed from the severity of his injuries.
According to police, "Detectives are investigating whether illicit drugs played any part in the suspect’s actions."
The suspect allegedly gave detectives a fictitious name of "El Baker," but he was identified as Kraemer through fingerprint comparison. The suspect, who recently moved to Portland from Georgia, was arrested and charged with second-degree assault, police said.
