Nothing justifies murder, never and will never
But accepting the fact because of the country we are in and answering your question,

Will this case end up like other cases where the government does nothing about the inhumane act?

Yes, I have followed quite number of similar cases and the trend is always that maybe we get to hear of the first and second arrest and then, the media stops talking anything about it and that's it
Most times, the assailants are released without the knowledge of anyone
That's how bad the country is
Too sad
