Did he do us all a favour?

Eric Dacosta, 52, jumped the gun. He killed Paul Stephen Darmetko, 42, in Florida and then cut up the corpse because – he told the cops – he thought Darmetko could be the next mass killer.

So Dacosta shot his roommate in the back of the head, covered the head with a plastic bag and then secured it with a belt around the neck to stop the bleeding.

He then dismembered Darmetko’s body in a bathtub to “make him smaller” and dumped the remains in a canal.

He’s now facing charges of murder and abuse of a dead body.
