A crime has been committed in my house

The victim, at the scene. The perimeter shows sign of a struggle between the victim and the perpetrator. The victim is deceased and has been laid to rest. Sadly, it was not possible to identify the victim, meaning next of kin have not been notified.

Suspect #1. Photo taken days before the crime. Suspect appears relaxed.

Same suspect after the crime has taken place. Suspect appears indifferent to the pain and suffering that has taken place only a few feet from where he is resting. Is it possible to be this cold blooded?

Suspect #2. The suspect has not been seen since the crime, but is known to often hang out at the premises.

Suspect #1:
Motive: suspect appears to be a cat
Alibi: even though suspect has been interviewed repeatedly, he has refused to state his whereabouts at the time of the crime.
Wrap sheet: suspect is known to have bahaved violently towards rodents, insects, birds, yarn, house plants and other guests. Suspect has never shown remorse for any crimes, even after eating the victims.

Suspect #2:
Motive: clearly a cat
Alibi: suspect #2 has not been apprehended.
Wrap sheet: suspect is a multiple convicted felon, having murdered bees, wasps (this is technically not a crime, but still), mice.
Means: suspect is likely not equipped to overcome a foe as large and powerful as the victim. Should still be considered as a possible perpetrator behind countless killings, leaving behind dead bodies or, in most cases, a gall bladder.

In conclusion, evidence points to suspect #1, but is circumstancial.
