Several chilling details have emerged in the cold-blooded murder of the partially disabled Pune teenager, Chaitanya Balpande, who was allegedly beaten to death by his mother and her alleged boyfriend last week. Investigations and statements from family members have led the police to suspect that the 13-year-old's murder had a rather sinister motive: Rakhi Balpande (36), wanted to claim a Rs. 10-lakh insurance policy that was in Chaitanya's name.
