That's the part of hard-to-trace complicated modus operandi. Having four separate modi  operandi which look like accidents is a very complicated strategy and quite hard to go with it - requires many skills. In fact, it's one of the most undetectable modi operandi on the show, among with Dexter's own few different and Meridian's driven suicides. A fewer serial killers in real life, in fact, are that smart to go untraced for a few decades - it usually requires them to have an untracable pattern - while most of them are show-offs it's usually hard for them to maintain it without having a few mistakes which eventually will lead investigation to them. The most prolific serial killers are not only lucky and smart - they often change the pattern, that's why many serial killers have alleged murders which can't be proven right. By the way, the reason why USSR had some of the most notorious serial killers in the 80's and later Post-Soviet countries had quite a few in 90's and 2000's is very simple - in USSR till the 80's serial killers were declined to exist in the country (known examples were top secret cases, especially in 70's when there were at least 20 really prominent and really bad serial killers).
