He was one of the 20 doctors involved in the nanobots facelift trial. Dr. McCann attempted to hide the side effects, where some donor patients died from heart attacks and some of the recipients were horribly disfigured. His medical license was subsequently revoked when these details came to light.
One of the trial recipients, Eric Lathem discovered that Dr. McCann was still practising and blackmailed him into fixing the disfigurement on Lathem's face.
During the investigation into the death of Brian Barrow, Detective John Kennex and Dorian questioned an informant Detective Kennex has used in the past, Di Carlo. They were looking for information on illegal high-end plastic surgery. Di Carlo mentioned a guy located in the East Term who could reportedly change someone's face so that facial recognition could no longer recognise that person.
The investigation led Detective Kennex and Dorian to the laboratory of Dr. McCann, where security measures alerted Dr. McCann about their presence. Dr. McCann injected himself with synthethic adrenaline and attacked Detective Kennex. He showed remarkable strength during the fight and had been choking Detective Kennex when Dr. McCann went into cardiac arrest and died.
