Accidentally touched a lady with my bike and she is dead

I am a 22 year old student. It was raining on the day of the accident and I accidentally touched an old lady who is 65 years old. She was crossing the road with other woman, which actually wasn't the place to cross the road. She was not crossing on the zebra crossing too. After touching the lady, she became unconscious and I immediately called their family members and helped her rush to the hospital. Later that day 4 hours after the incident the lady passed away. I did not know that an FIR had been lodged against me. I got arrested and got released on the station bail too. This incident happened in Bangalore, Karnataka. It was not at all my mistake. I tried honking multiple times but they did not listen and the lady was negligent too. Nothing major happened to my bike too. My number plate just got bent after hitting the lady. So you can assume what kind of speed I was in. Will I face imprisonment or any other punishment. It was not my fault at all. Sections 279 and 304A were imposed against me.
