Treachery present when accused executes crime without risk to himself

It is beyond doubt that appellant are guilty of murder. We agree with the trial court's appreciation of the qualifying circumstance of treachery in view of the fact that the initial assault on Sabino was made from behind and was unexpected. Appellant undoubtedly employed a method in the execution of the crime which tend directly and specially to insure its execution without risk to themselves arising from the defense which Sabino might make.
