Case #3:
Case of The Snack Shack
8th Grade Forensic Science
http://kids.mysterynet.com/quicksolve/
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."
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?
Mr. Levine had just put up his poster about the price
increase that morning. Nathan and Trevor said they had
been fishing since dawn and had spoken to no one. Since
Trevor knew that a dollar bun was now a dollar and ten
cents, he must have been the one who broke the window
and got inside the back room, where he read the poster
lying on the old desk.
