I ENTER THE GARDEN THERE ARE 34 PEOPLE RIDDLE

If the backyard and garden are two different locations then there would be one person left in the garden. This is because the murderous rampage took place in the backyard, not the garden. However, the riddle solver considers that the backyard and the garden is the same place then, then zero people would be left, as the killer would technically be counted amongst the 34 people.
