Thomas Murphy was an inmate at the Fiorina 161 Class C Work Correctional Unit, one of several who stayed behind after the facility was officially closed down by Weyland-Yutani. He was killed by a lone Xenomorph that was born in the prison in 2179.
Murphy was the Xenomorph's first victim, rolling into a large ventilation fan when the Alien spat acid in his face.
He spent most of his early life on the run from the law. A conversation between Frank and Murphy in the assembly cut implies that he has been sentenced to prison for sexual deviance and probably abuse as well. He appears to have a shorter prison sentence than most and often volunteers to help in efforts (like finding survivors from the EEV) in attempts to shave a few months off of his sentence. He is the first person killed by the Alien. He is first introduced in the theatrical cut searching the EEV for survivors with his dog, and later mourns over it after the alien emerges from it (though he thinks a human did it). Later, he is seen cleaning the giant air ducts of the prison. He steps on the aliens shed skin and is clearly disgusted by his find. He hears noises coming from a hole in the wall, and goes to investigate, believing it to be his dog, Spike. He soon realizes it is not his pet pooch but a juvenile Alien. Before he can pull his head out of the hole, the alien spits acid into his face. He staggers backwards in agony and accidentally tumbles into a large spinning fan, killing him instantaneously.
Behind the ScenesEdit
The song Murphy sings while cleaning the vent shafts is "In the Year 2525" by Zager & Evans. In the comic adaptaion, Murphy sings "Paint it Black" by the Rolling Stones.
In the theatrical cut, Murphy's dog Spike is the victim of the Facehugger, resulting in an Alien with more mammalian features. However, in the assembly cut of Alien3, the dog was not the creature attacked and impregnated, and Spike is in fact never seen in this version of the movie.
Differences in ComicEdit
Instead of cleaning out an airduct like in the film, the comic has Murphy mopping a floor when the creature spits acid in his face while he's near an intake fan. Instead of being pulled in Murphy was decapitated.
