60% of murder cases result in someone getting arrested. So we still have to ask: a) how many of those arrests result in a conviction? b) how many of those convictions are of the right person? c) and how many murders result in murder cases? A murder case basically starts with police opening a file saying "X has been murdered" and goes on from there. So if the death looks enough like accident or natural causes or suicide, no murder case is opened and it doesn't count as an uncleared murder. Therefore it wouldn't surprise me if the majority of murders (51%, anyway) are unsolved.
