She later gave birth to a daughter who stayed with her mother at her parents’ house. Thereafter, my brother started to live with the accused woman. My brother left for his duty around 2.30pm on May 16, and when he came home around 8pm, he found the girl dead. When he asked the wife about the incident, she did not tell him anything.
