But when Maben began showing his laziness and willingness to not do nothing to Maureen's daughter, the pair moved back home. When the daughter announced in 2008, she was pregnant, Maureen asked the couple to leave their home, trigging Maben's urge to murder her. In 2009, the crime was committed. Members of the immediate family and friends of Maureen discuss the brutal and calculated murder of a pillar of the local community.
