Nairobi - A Kenyan court on Tuesday sentenced a Masai tribesman to death by hanging for stabbing to death his pregnant wife, then eating her liver and part of her heart.

Police who arrested Lolwakenju Lengironi in September 2001 in a Nairobi slum found him with blood on his mouth, standing near the mutilated body of his wife, Mangenyan, court papers said.

Witnesses at the trial testified he stabbed her in the chest in a dispute, although prosecutors did not give any motive to the killing, paper said.

His lawyers argued he was under the influence of alcohol and temporarily insane at the time, but the jury of seven rejected the argument. Lengironi has 14 days to appeal the sentence.
