This one should be fairly easy :).
Besides a bowl of what looks like baby puke and a rotting apple beside it, what does the dead body show us (2 things) and what does that tell a forensic investigator?
Forensic Guesswork 3.
Here we have a dead child with wounds/marks on the side of her neck.
Without Googling, 1. What do the wounds/marks tell you about how she died and 2. What caused them?
Again NO Googling! That's no fun...
I'll spill the beans after we see some take a gander at this one to test their forensic...
