Let's see now . . Lisa =1, Frank =1, 1+1=2, times 3 gunshoots = 6. Jim =1. 6 x 1=6. 72 rooms divided by 6=12.
12 divided by Lisa,Frank, and Jim =4. 4 people in the house = Lisa,Frank,Jim, and Mary. Mary is shot 3 times. 3 people are
"un"-shot. 4 people total - 3= 1. 1 is the number of rooms checked before finding Mary. Mary is number 1. It's her.
Conclusion : Mary shot herself three times because Jim was sleeping in the foyer.
