Cases of spouses killing each other have been on the rise in the country.

In June, Riziki Cherono was arrested at the coast for planning the murder of her husband, Kenyan based Dutch tycoon Herman Rouwenhorst.

The middle-aged mother of two plotted her husband's killing and even opened the door to the killers on the night Mr Rouwenhorst died.

A similar incident occurred in Kuresoi on July 31st when a man killed his wife and her lover after finding them in the matrimonial bed.
