What to do if offender is not coming on court dates of cheque bounce

I am a govt servant. i had given the contractor some amount only to return after one month as he had no money to run the contract. I took a cheque in advance without date and name but with due amount filled. He did not return money and ran away without completing the contract also. Since I am Govt servant, I entered my sister's name and tried to encash the cheque. But it bounced. My sister filed a bounce cheque case against him. Legal notice was sent through email and by post also. But he did not reply. Till date 3 hearing were called. He did not appear and is absconding. What to do next?
