Algodoo

I really dont have any idea what happened since theres no indication of what happened before this, but I can try

RN we have 16 suspects

Pitore is the victim, so that drops it down to 15

Many items have been covered in blood, which is likely the culprit trying to throw us off

The bowling ball was in the wrong room, so thats ruled out. The pickaxe goes against the body analysis, so unless it was used a different way, thats out, and the frying pan kinda seems like a red herring but its the most likely weapon

Its never indicated whats inside the locked door so thats currently useless info

Im pretty sure the ceiling railing means the killer was up there

I dont know what the magnet or boomerang have to do with anything, but Im pretty sure the killer was the one who duct taped the broom and pickaxe together and the one who went to the girls locker room

I dont know if puppy was a typo, but its not looking good for the puppet lady

Sorry for things that didn't got an important thing to mention, Algodoo crashed for some reasons
The locker had inside the puppet missing an arm
There should be another used duct tape(60cm)
The key is only for the female locker room(respectivly Patorishia's key)
The magnet also had duct tape, that's when it crashed and forgot about it
A gaming key was also in the locker
