A fire of an unknown origin took the life of an 83-year-old woman during the wee hours of Monday morning. Eighty-three-year-old Norma Semple was killed on Monday when her Block 22, Wismar, Linden home was consumed by fire. The Guyana Police Force, in a statement, said the fire occurred between 02:15hrs and 02:50hrs on Monday. Investigation has thus far revealed that Semple lived in the fully furnished one storey wooden house alone. According to a neighbor, Alita Prowell, she was inside her home when she heard a loud and continuously cracking sound which caused her to look through her window.
