appearance of struggle

There appears to have been a struggle. The struggle’s specifics cannot be discerned currently, but someone has died. Their death was determined by the presence of blood and bone fragments at scene of the crime. The species of the bone fragments cannot be determined currently, but something with vertebrae died, or was crushed somehow, which is unlikely to have occurred without death or serious disfigurement of the spinal column. Serious disfigurement of the spinal column typically results in death, at least in all known vertebrate organisms on Earth.

Was it possible that the struggle occurred off-planet? No known organisms currently containing bones can be found anywhere other than Earth, but it is impossible to rule out the possibility that alien time travel could have been involved in the struggle. Then again, the vast majority of struggles involving blood and bone fragments occur on Earth, with known species as the combatants. Yet the blood has not been tested to discern the specific species, nor have the bone fragments been tested for DNA. Therefore alien or off-planet interference cannot be conclusively ruled out as intervening factors in the yet-still-unspecified struggle. Further reporting may be forthcoming following an actual investigation of the scene.
