  • Slide 18: I know the correct answer for why David seemed to think the man was a thief, but while David’s assumption was a legitimate possibility, I don't believe David had enough data to yield conclusive results...the strange man's behavior mirrored that of my own when traveling with company and limited keys or key-cards...which leaves the man's speech, and the speech can be used to support either scenario (Man=Thief or Man=Mistaken).
    Here’s why:
    When observing the strange man's speech, one might deduce that his choice of the word 'my” indicates a lone traveler without company in his room, which fits nicely with scenario A because that would contradict his behavior (knocking); however, when considered in conjunction with the remaining data, one might alternatively deduce that the man didn’t feel compelled to divulge personal information regarding his travel partners or guests, thus avoiding words like “our”…a simpler explanation yet: he considered the room as his whether he shared the room or not.
    The only remaining data is the last bit of dialog and action wherein the strange man assumed to have the wrong floor and went for the elevator. This data is neutral because it supports scenario A if the man is being deceptive (and successfully so), and also fits scenario B if the man is mistaken.
    I like the slides so far, but this one just seemed a little incomplete to me. Please correct me if I’ve missed something.

  5. 5. Snack Shack 8 th Grade Forensic Science T. Trimpe 2006 http://sciencespot.net/ Case #3 Can you solve it? Daily CSI
  6. 6. Harborville's Beach Snack Shop had been open only an hour when Max stopped in and noticed a new poster announcing a price increase. "I put the sign up this morning," Mr. Levine told him. "I had to raise my prices 10% because I have so many new expenses. Like now I need a new window for my back room. Somebody broke it, trying to get into my store last night." "Have you called the police?" Max asked. Mr. Levine replied, "No. Nothing was stolen." He led Max to a small storeroom in the back and said, “I use this space as an office. Sat here and made my price change poster last night. Soon as I was done, I left it on that old desk. I locked the door to the main part of my store when I left, so whoever got in was stuck in this little storeroom. There’s nothing here to steal." Source: http://kids.mysterynet.com/quicksolve/
  7. 7. When Max left he wandered down to the break wall, where Nathan and Trevor were fishing. "Did you hear that somebody broke a window at the Shack?" he asked. "Nope," Nathan said. "We've been here since dawn and haven't talked to anybody." Trevor gestured to the bucket. "We've caught some big ones." Nathan stood. "But now I'm starving. I've got a dollar left from my allowance. If Mr. Levine is there now, I'm going up to the Shack to get a Big Beach Bun." "Better get another dime from somewhere," Trevor told him. "A dollar's not enough any more. As for me, I'm going home to get a couple sandwiches for myself." "You both stay right here," Max said. "I know which one of you broke that window. You'd better think of a way to pay for it, because I'm telling Mr. Levine." How did Max figure it out?
  8. 8. Mystery Footprints 8 th Grade Forensic Science T. Trimpe 2006 http://sciencespot.net/ Case #4 Can you solve it? Daily CSI
  9. 9. One Saturday morning Nina saw the three musketeers in the mall. Jenny, Brittany, and Mitzi called themselves by that name because they always were together. "I've been shopping for sandals," Jenny told Nina. "But I have such a wide foot nothing seems to fit. We've been looking everywhere." "And it's been slow going," Mitzi added. "On account of Brittany's-" "I know," Nina said looking at Brittany, "I heard you sprained your ankle in gym yesterday. Does it still hurt a lot?" "It's okay as long as I move really slowly," Brittany told her. "We're going to get ice cream at the Just Desserts Shop now. Want to join us?" "Better not,” Nina said, “ Max is meeting me at home. See you later." Source: http://kids.mysterynet.com/quicksolve/
  10. 10. Nina was taking a short cut through Harborville's city park when she saw Mr. Hansen kneeling beside a new sidewalk. The city maintenance man frowned as she drew closer. "Somebody jumped right in the middle here while the cement was still wet," he said, pointing at two narrow footprints embedded in the concrete. "Now I'll have to rip out this section and re-do it. Sure can't leave the sidewalk looking like this!" "Any idea of who did it?" Nina asked. "A kid over there on the slide said that girls named Brittany, Mitzi, and Jenny were the only ones near here. But he doesn't know which one ruined my sidewalk." "I know who did it," Nina declared. How did Nina figure it out?
  11. 11. Surprised Visitor 8 th Grade Forensic Science T. Trimpe 2006 http://sciencespot.net/ Case #5 Can you solve it? Daily CSI
  12. 12. The clock in the courthouse ahead of Max showed six o'clock. As it began chiming, he noticed a tall man with a briefcase walking towards him. The man turned around, looked at the clock, and then quickened his steps. He took an envelope and dropped it in a mailbox as he continued on. Max moved faster, too. Miss Fritz had invited him for dinner. He didn't want to be late. "I'm glad you could come," Harborville's oldest music teacher said. "I've made a lovely salad for us." She gestured Max to a chair. "Good thing I prepared ahead. A surprise visitor just left." "Who visited?" Max asked. "A teacher from Harborville's School for the Deaf,” she replied. “He was totally deaf himself; poor man, but he could read lips perfectly. He had the loveliest penmanship when he wanted to tell me something." Source: http://kids.mysterynet.com/quicksolve/
  13. 13. "Why was he here?" he asked. She said, "Well, evidently the school is low on funds. I was glad to help out. I had just cashed my social security check so I was able to give him five hundred dollars." "Did he just leave?” he asked. “Was he a tall man with a brief case?" "Yes," she replied. "We'd better phone the police. I think that man was a phony. I know for sure he wasn't totally deaf." How did Max figure it out?
  14. 14. The Broken Window 8 th Grade Forensic Science T. Trimpe 2006 http://sciencespot.net/ Case #6 Can you solve it? Daily CSI
  15. 15. One evening as Max was out walking, Mrs. Zenitt called his name. He hurried across the street. She was standing in her front yard, but she guided him around to the back. "I was watching TV in the living room," she told him, "and I heard a crash. Just look!" She pointed to her back porch window. "Someone threw a rock through it. It's broken into a dozen pieces!“ "Do you know who did it?" he asked. "No,” she replied, “He ran off, but I think maybe it was David Loring. We had a spat the other day because I told his parents he had to stop using my yard as a short cut. But I wouldn't accuse him of breaking a window without more proof.“ "I'll talk to him," Max said. Source: http://kids.mysterynet.com/quicksolve/
  16. 16. He found David panting as he bounced a basketball under the light on his garage. "Did you just run from Mrs. Zenitt's?" Max asked. "Did you break her window?" David shook his head. "No. I'm all out of breath because I've been out here shooting baskets. I don't know anything about a broken porch window." "You're not telling the truth," Max said. How did Max figure it out?
  17. 17. Stranger Danger 8 th Grade Forensic Science T. Trimpe 2006 http://sciencespot.net/ Case #7 Can you solve it? Daily CSI
  18. 18. David was sitting in his hotel room reading a book, when he heard a knock at the door, and the sound of someone trying the door handle. He opened the door, where he saw a man whom he had never seen before. The man said, "I'm terribly sorry ... I thought this was my room. Wrong floor, I guess." He then walked off down the hall toward the elevator. David went back into his room, thought about what had just happened, and then phoned the front desk, suggesting they call the police, since the man at the door had obviously been a thief. Why was David so sure the man had been a thief? Source: http://kids.mysterynet.com/quicksolve/
