Solution 1: Water in the Wound
"…Lenny Osborn."
"Osborn?" you ask surprised. He was the nicest out of the bunch. "How do you know he's the murderer?"
"Simple," L answers. "I know because of the murder weapon."
"The murder weapon?"
"An icicle."
Suddenly it all makes sense. "It melted," you say.
"Leaving water in the wound," L finishes your thought.
You smirk. "And the icicle was made from leaking pipes in a freezer, like the freezer where Lenny Osborn keeps his ice cream."
"Correct," L says.
You order the sheriff to arrest Mr. Osborn, explaining your reasoning.
It doesn't take long for Mr. Osborn to crack during the interrogation. He confesses, and you've just completed your first case.
A/N: I got the idea of using an icicle for a murder weapon from the book The Westing Game (the best book ever!). Anyway, there's one part in that book where Sandy tells a story about someone getting stabbed with an icicle.
Let's see how you did!
Correct: Charli-san
Very close: theoriginalpickle, Akito-Aya
My favorite answer: Akito-Aya – Eating the murder weapon…creepy and yet I love it.
Case 2 should be posted shortly.
