Fearing that they will lose their home in a loan default case, a teenage girl and her mother committed suicide by setting themselves on fire in Thiruvananthapuram's Neyyatinkara area today. Strangely enough, they had already paid off Rs. 8 lakh towards a housing loan of Rs. 6 lakh taken from a public sector bank about 15 years ago. Vaishnavi, 19, and Lekha, 40, suffered 90% burns in the incident. The girl's father, Chandran, was away at the time.
