I would like to start from beginning, my sister was murdered by her in laws on 23rd March'12. We lodged FIR on 23rd March'12 under section 304 498a. On 26th March'12 her husband surrendered to Police and other family members were absconding. on 23rd June'12 Challan came from police that her husband is responsible under section 304 498a and 406 and investigation was kept pending under 173 crpc for others. When we went to Investigating Officer he told that he has submitted final report for the case to SP wherein he found that no other person other than her husband is responsible for the death as on 4th July'12 but in court the final report is not submitted till date the next hearing is on 30th July.
I would like to mention that my sister used to write Diary which is with the police and police says that in diary your sister has not mentioned the names of other accused except her husband hence others are not responsible for the death
Please guide me what we should do now? and how we should proceed to enter the names of other accused in the case...Please help me out!!!
