I walked the park today, it is not closed, there is no police tape. I walked the whole perimeter of the park and found where I believe he was discovered. There is a large drainage pipe. It is vertical in the ground, the grate over the top was removed and the area all around it was completely trampled by footprints (I assume law enforcements). It is the only area of the park to have noticeable footprints after the rain. The pipe is a couple of feet in diameter. This would explain why the rain played a roll. The pipe can not be seen from any well traveled part of the park. It can not be seen from google maps. It also explains how they got the body out with no one noticing. They could pull a van up onto the playground and walk up the path to the school from the park.
