How a Chief case works

A murder has occurred in a house with 5 rooms. 7 people — the suspects and the victim — were each in a different row and a different column of the 7×7 floor plan, exactly like a sudoku. Every suspect gives you one positional clue ("on the carpet", "beside a table", "in front of a window", "in the Kitchen"). Place everyone, find who was alone in a room with the victim, and accuse the murderer.
