PATNA, Jan. 23 -- With no breakthrough in the death of the Jehanabad NEET aspirant, the Forensic Science Laboratory (FSL) has stepped up its probe to establish the line of medical treatment, medicines used and traces found, besides possibility of assault or blackmailing. "The FSL has done videography and photography of the hostel room and recovered whatever it could lay its hands on. The blood stains or sperm sign, if any, on the girl's clothes will also be examined," police said. Police could reach the room of the girl on January 9 only, while she was admitted to hospital on January 6 itself, which could make probe a challenge, as one didn't know what happened in that room in three days and if it was cleaned," an official said....
