THE CASE OF THE ELEVATOR KILLER

   Cory Matthews was found bludgeoned to death on Tuesday morning at 
7:30am. His body was discovered in the elevator when it arrived on 
the third floor of Cory Industries. There was one elevator for 
the five story building and only a few people were in the building 
at the time of the murder. Detective Core arrived on the scene 
and was assisted by nighttime security guard, Dero Yermenjian. 
   "Due to a rash of computer theft recently, building management 
started a new security policy," offered the security guard. "Anyone 
who enters the building after 6:00pm and before 9:00am has to sign in 
with me at the front door. Here's the sign-in book itself. It'll show 
you who was here this morning." 
   Detective Core noted that only three employees had arrived just 
prior to the time of the murder. 
   "I don't see Mr. Matthews' name in the log," noted Detective 
Cordero. 
   "He's the boss. I wouldn't dare make him sign in," laughed Dero. 
"But I do remember he got here just before 7:30. He seemed to be in 
a hurry. He immediately went around the corner to go to the elevator 
bank and that was the last time I saw him alive." 
    Mr. Matthews' son-in-law, Chris DoHer was the one who discovered 
the body. According to the log he entered the building at 7:00am and 
went to his office on the third floor. However, at 7:30am he left his 
office to take the elevator down for coffee He pressed the button for 
the elevator and when the doors opened, Mr. Matthews was lying in a 
pool of his own blood." 
    "It was dreadful," cried Chris. "There he was lying face down. 
His gray suit was practically soaked with all the blood." 
    "Do you always get to the office at such an early hour, 
Mr. DoHer?" the detective asked. 
    "Not usually," he answered. "But Cory asked me to get here early. 
He claimed to have figured out who was responsible for all the theft." 
    The second employee to sign in was Bullseye Aim, a new hotshot 
saleswoman who had been with the company a few months. He signed in 
at 7:28am, but never claimed to see Cory waiting for an elevator. 
    "I never take the elevator," she bragged. "Ask Dero, the security 
guard. He sees me every morning. I have to keep in shape. That's the 
nature of the business. Look good, dress sharp. You know what I mean? 
There's a set of stairs at the end of the elevator banks that I run 
up to the third floor." 
     "When you got up to the third floor did you see Chris DoHer 
waiting for an elevator?" 
     "Sure did." She answered quickly. "He asked me if I wanted to 
go with him, but I already had with me my super sized mocha Cocoa 
Blast. That was all the coffee I needed." 
     The third employee to sign in was Bio Goat, Mr. Matthews' 
executive assistant. She signed in just after Bullseye Aim at 7:29am. 
    "I could have saved Mr. Matthews' life," cried Goat. "When I 
entered the lobby, I thought I saw Mr. Matthews turning the corner to 
go to the elevators. Dero confirmed that it was him, but he wouldn't 
let me go after him until I signed that stupid book. By the time I 
got to the elevators, Mr. Matthews was already gone." 
    "Did you hear or see anything else out of the ordinary?" the 
detective asked. 
    "Nothing else out of the ordinary," she answered. "I heard 
Aim walking up the stairs." 
     "Are you sure it was Aim?" questioned Detective Cordero. 
    "Oh, sure," answered Goat. "That bundle of energy. I'd know 
his walk anywhere." 
     "I wonder," Detective Cordero answered to himself.
