Bail for suspect under section 302

Hello, Last month, my brother was falsely accused of committing a murder. The scenario was such that my brother had a verbal argument with a neighbour one evening after which he left the neighbourhood for some work and returned home late at night. The neighbour was under heavy influence of alcohol and had shown repeated signs of abnormal behaviour prior to this incident which was common to other members of his family. Early next morning the police visited my house, took my brother to the police staion and started questioning him about the argument he had last evening and whether there was any physical harm. They kept on questioning him until the afternoon after which they told him that the person with whom he had an argument visited a nearby hospital with signs of physical harm for which he was treated and he passed away later on in the night. However before dying he called the police to the hospital and gave a statement that he was hit brutally by the person with whom he had a fight earlier in the evening (indicating my brother). However the time of the fight mentioned by him in the statement was much later on when my brother was away and occupied with his work. Also his statement does not have any signature or videogrphic evidence. My brother was kept in police custody for 3 days in which he was thoroughly interrogated by the police to their satisfaction and was later transferred to the state prison. It's been a month since the incident and I am running around to get him out on bail. I am being told very confusing things by different people. My sister in law who was with my brother during the time has given her statement along with time and location and requested the police to check the numerous cctv cameras that can verify his location which can also be verified by cell phones carried by my brother. I have also forwarded a request for this to the office of the police commissioner upon the advise of my lawyer. My immediate concern is to get him out on bail and to get the cctv footages verified by the court before they are over written by newer videos. However his bail plea has been rejected by the sessions court. Is it possible for me to move to the high court for immediate bail ? Imp thing here is that no one from the deceased perons family is filing any case. The FIR was registered by a police constable who took the statement.
