Task: Question Answering
Input (English): Passage: Steve Everett, an Oakland journalist recovering from alcoholism, is assigned to cover the execution of convicted murderer Frank Beechum following the death of Everett's colleague, Michelle Ziegler, who had originally been assigned to the story.
Everett investigates the background to the case and comes to suspect that Beechum has been wrongly convicted of murdering Amy Wilson. He gets permission from his editor's boss to investigate, and is told that the top editor would call the Governor, and that would do the job, if Everett gets hard proof. He thus has a little over 12 hours to confirm his hunch and save Beechum.
Everett interviews a prosecution witness, Dale Porterhouse, who saw Beechum at the store with a gun. Everett questions Porterhouse's account, saying that, because of the layout of the store, he could not have seen a gun in Beechum's hand.
Everett confronts D.A. Cecelia Nussbaum, who reveals that, a young man, Warren, was interviewed and claimed he had stopped at the store to buy a soda and saw nothing. Everett decides that Warren, never called as a witness, is probably the real killer. He breaks into the deceased reporter's house, suspecting that she had been onto something and finds her file on Warren. Meanwhile, Warden Luther Plunkett also starts to have doubts about Beechum's guilt.
Everett falls out with his bosses and is fired on the spot, but he points out that his contract entitles him to adequate notice. They ask him how much notice he requires, and, looking at his watch, he says 6 hours and 7 minutes. He tracks down Angela Russel, Warren's grandmother. She tells him that her grandson could not have been the murderer, and berates him for the lack of interest from the press when Warren himself was killed in a mugging two years after Amy's murder. 
Question: What is the full name of the person that claims Dale Porthouse could not have see a gun in the store?
Output (English): Steve Everett.
