Why was Balram labelled as murderer?

Balram fashioned a weapon from a broken whiskey bottle, and lured Ashok from the car. He rammed the bottle into Ashok’s skull, and then stabbed him in the neck, killing him. He stole the red bag, filled with 700,000 rupees, and escaped with Dharam to Bangalore.
