Dr. Shaun Murphy (Freddie Highmore) will come face to face with a murderer in “The Good Doctor” Season 1, episode 15.

In the promo released by ABC for the yet to be titled installment, Dr. Neil Melendez (Nicholas Gonzalez) tells his fellow doctors that his patient needs a liver donor in order for him to survive. Dr. Claire Browne (Antonia Thomas) later on tells Shaun that they’ve found a match.

However, Claire also revealed that the young patient’s donor is a man from prison. The unnamed character will be taken out of jail and transported to the hospital. Shaun is anxious at the idea that a murderer will go to the hospital where he’s working at.

In one of the scenes from the 15-second clip, it is revealed that the murderer has plans to escape from prison. After his handcuffs are removed, he points a gun at a hospital staff. During the incident, Claire and Shaun are in the same room.
