Police said DNA samples of Mosim’s mother, Akbari Begum, were matched with unidentified bodies recovered in Fatehpur, Kaushambi, Banda, Kanpur Nagar, Raebareli, Pratapgarh, Amethi and Chitrakoot, but no match was found. Investigators said the exercise was also constrained because biological samples from several bodies had deteriorated over time, limiting the scope for forensic comparison.
