Question

Imagine that you are at a crime scene. You find skeletal remains, but the skeleton is not complete as some of the smaller bones are missing. The bones are within a twenty feet radius. Based on this information, what would you be able to ascertain about the time of death and the individual who was killed

Answer 1

no we can't

well the murderer can kill the target 30mins ago disperse the bones in radius of 20m
he can also kill the target 3days ago and disperse the bone in radius of 20m

so we can't really comment on the time of death and the murderer(cause murderer could be anyone) with just this much information
