I'm fairly sure even straight forward murder cases take quite a while to investigate, get to court and count as solved. Considering these stats are taken on the last day of that year, I'd be surprised if many of the murders in the preceding days, weeks, even months had yet been officially solved. In fact the document has some statistics about time taken to solve cases, with 100 days being a timeframe used for comparison - so no wonder all those murders on 30th December hadn't been solved by the end of the year!
