The Killer Isn't June

Everyone thinks June did it.
Her access credentials were used near the crime scene. Her name appears in the victims notes. Witnesses heard the argument. And for twelve crucial minutes, June cannot prove where she was.
It looks like an open-and-shut case.
It isnt.
Hidden inside a field of 43,000 suspects is the one person who actually killed Marcus Vale. Before he died, Marcus left behind 17 precise clues. Each clue eliminates part of the suspect pool. Some remove only a few names. Others erase thousands at once. And one tiny detail clears June completely.
Your task is to follow the evidence, test every assumption, cross out the impossible, and keep narrowing the field until only one identity survives.
This is not a mystery you simply read.
You solve it.
No trivia. No guesswork. No outside knowledge required. Every fact you need is inside the case. The challenge comes from spotting patterns, checking contradictions, understanding what each clue really means, and refusing to be fooled by the suspect everyone else believes is guilty.
As the list shrinks, the pressure grows. A harmless-looking letter becomes decisive. A number wipes out entire groups. A surname pattern changes everything.
17 clues. 43,000 suspects. One killer.
Can you clear Junes name and unmask the murderer before the final reveal?
