Detective John Mulchaey was played by David Keith in the Carrie (2002) remake.He is the person responsible for the investigation regarding the Black Prom. He is meticulous and, through interviews with the survivors and evidence he collects from the scene of destruction and death, he manages to reconstruct, what happened at the prom. He finally begins to suspect through Miss Desjardin, that Carrie was behind the destruction, which lead to 234 confirmed deaths and 7 unconfirmed deaths and one disappearance (Carrie White), who is also assumed dead.
It is implied, that in the planned tv series he would find out, that Carrie is alive and would be the man responsible for capturing her. This planned tv series, however, was never materialised.
