Investigation : Two Pills

[Deepak Kiran]

A serial killer kidnapped people and made them take one of two pills, one was harmless, and the other was poisonous. Whichever pill a victim took, the serial killer took the other one. Each time, the victims died and the serial killer survived.

Question. How did the killer always get the harmless pill?

 

[Beryl]

The poison was in glass of water not in pills

 

[URum]

Old one poison is in the glass of water

Here comes my shrewd brains.If I was killer no chances no probabilities. No wasting water.

Two pills also poisoned. Once the victim took one pill and died.
How he knows how I took the pill. I will discard all the poison in the pill out and have only the capsule. So Im always last one standing.

Rapunzel is so good in committing crimes... May be no one can catch her if she does crime with this brain... So be careful never mess with her

Poison is in a glass
