The incident took place in Yacharam village of Vikarabad district.Vikarabad police said they received information on Jan 25 about the deaths of a couple, N Dasaratham (58) and his wife Lakshmi (54), at their residence in Yacharam. Initial information provided by relatives suggested that Dasaratham had died by suicide after consuming poison, and that Lakshmi passed away soon after, reportedly due to shock following her husband’s death.
