(1.) The appellant stands convicted under S.302 of the Penal Code (for short, 'the Code') and sentenced to undergo imprisonment for life for commission ' of the murders of his wife Maina and his son Juja under painful circumstances during the night of Aug. 30/31, 1980, without any motive and for no rhyme or reason, by means of Barsi (M.O.I.) and a Katari (M. O. II) while he had temporarily gone to the house of his father-in-law with his wife and child for taking new maize. The actual commission of murders had not been witnessed by anyone.

I and II stained with blood lying near him. These articles, on chemical and serological tests, contained human blood.
