Forged Will bearing genuine testator signature

The image below is part of a disputed Will where FDS was able to determine that, while the signature was genuine, the document as a whole was not.  The printed text was produced after the signature had been written and well after the death of the testator. 

The perpetrator had taken advantage of a blank sheet of letterhead paper signed by the testator before his death with the intention of it being used for correspondence while he was away on business.
