Question

who is the \criminal\? (the three boxes left unchecked will reveal the crime. if you cannot figure it out, you may be next.)
the players
students astro, mrs bio, mr chem, dr earth, coach physics, miss zoo
the last known whereabouts
atrium, gym, kitchen, library, movie theater, pool
the method
chemical poisoning, cougar attack, electrocution, fallen object, stubbed toe, venomous bite

Explanation:

This is a logic puzzle where we need to match players, their whereabouts, and the method of crime. Let's assume we have to use logical deduction (like in a grid puzzle, similar to Sudoku or logic grid problems).

Step1: Identify the categories

We have three categories: Players (Students Astro, Mrs Bio, Mr Chem, Dr Earth, Coach Physics, Miss Zoo), Whereabouts (Atrium, Gym, Kitchen, Library, Movie Theater, Pool), and Method (Chemical Poisoning, Cougar Attack, Electrocution, Fallen Object, Stubbed Toe, Venomous Bite).

Step2: Look for clues (though not fully visible, assume standard logic grid)

Typically, in such puzzles, we eliminate possibilities. For example, if a player is associated with a certain method or location, we cross out others. Let's assume we have to find the correct triple (Player, Whereabouts, Method).

But since the full clues are not given, maybe from common logic puzzle setups: Let's suppose Mr Chem is associated with Chemical Poisoning (since "Chem" and "Chemical" match), Kitchen (as kitchen is a place for chemicals), so Mr Chem - Kitchen - Chemical Poisoning.

Mrs Bio: Maybe related to Venomous Bite (Bio - biology, venomous bite is biological), Miss Zoo: Cougar Attack (Zoo has cougars), Dr Earth: Fallen Object (Earth - maybe object falls), Coach Physics: Electrocution (Physics - electricity), Students Astro: Stubbed Toe (Astro - maybe accident, stubbed toe).

But let's proceed with the most probable match: Mr Chem (Player) - Kitchen (Whereabouts) - Chemical Poisoning (Method).

Answer:

The criminal is Mr Chem, at Kitchen, with Chemical Poisoning (Player: Mr Chem, Whereabouts: Kitchen, Method: Chemical Poisoning)
