How did ausable kill max without a weapon?

Ausable cocked-up a story. He told Max that there was a balcony just below his window. He told him that the balcony was a part of the next room. When the waiter knocked at the door, Ausable told Max that it would be the police. Max was nervous. He dropped himself to the balcony through the window. But outside there was no balcony. He fell down and died.

hope it helps !
