Sharanya G S, 36, was found on the same hill three days later.According to the police, the missing Class 10 student, identified as Sreenandana, was part of a 40-member group, which included her parents. They said the group went to the Chandradrona ranges on Tuesday around 6.30 pm, when she reportedly went missing as darkness set in.Intensified search operationInitial search efforts by her companions failed to trace her, following which they alerted the police.Teams comprising over 30 personnel from the Forest Department and Fire and Emergency Services launched a night-long search operation using torches. However, the operation was suspended around midnight due to dense fog, poor visibility, and the challenging terrain of the forested hilly area.Also Read | ‘Was not afraid of elephants’: Kerala techie who survived 3 days in forest in Karnataka’s KodaguSenior police officers, including Additional Superintendent of Police Jayakumar, visited the spot and reviewed the search efforts.
