I have other stories I want to write; you can have this one.
On his way to the killing, the murderer finished his soda pop and threw the plastic bottle out the window of his vehicle.
It landed near the mailbox of our innocent protagonist, who found it in the morning and tossed it into his recycling bin.
Eventually DNA found at the crime scene will be matched to DNA found in our innocent protagonist’s recycling bin.
And oh! The adventures he will have as a result.
