Long time lurker, first time poster. I'd just thought I would chime in on the probability of the two bodies lining up with the Continental hotel. Sorry I'm terrible with maths, but this is how I would work it out:
- The distance between the bodies is approx 78460 meters.
- The distance in latitude is approx 76494 meters
- Lets use a grid system so that each grid square is 10 meters x 10 meters square
- So 76494m would be 7649 x 10 meter squares north to south approximately
- Lets make our grid 7649 x 7649 sqares
- Lets cut one of those dimensions in half because west of Perth is just water and has no real suitable dump sites.
- So we are left with a grid 7649 x 3824 made up of 10m x 10m squares
- The continental hotel is obviously a fixed point and the other two are variables.
- If there was only 1 murder, then the probability of the Continental hotel lining up with the body would be 100% obviously.
- When there is a second body added to the equation, it's a completely different story and the probability increases massively.
- Now the second body could be dumped either North OR South of the Conti, if South then no line would form (this is not really relevant though to calculation)
- The number of grid square in a 7649 x 3824 grid is 29,249,776
- There are approximately 8551 grid squares that the second body could be dumped in for it to line up with the existing two points.
- Therefore the probability of the body being dumped in line with the other two points is approximately 1 in 3420 or 0.029%
Maths wins.
