According to Wikipedia, the three serial killers with the largest numbers of victims are (or were) Colombians: Luis Garavito, Pedro López (the Monster of the Andes) and Daniel Camargo. This book describes the sickening lives and "exploits" of these beasts, along with some others, well known in Colombia, such as Nepomuceno Matallana ("Dr Mata"), a fake lawyer from the 1930s and 1940s who stole from his clients and then killed them (a TV Novela about Dr. Mata is currently being shown). There may have been more than 30 such murders. Although the book is turgid and often contains novelistic descriptions, it is mostly faithful in narrating the facts. The typical Colombian serial killer comes from broken families displaced by violence, with missing parents, where alcoholism and violence is present. He is transient. He moves quickly between smaller towns and villages and preys mostly on young boys or girls who, because of poverty and family neglect, are often by themselves in the streets. There, the killer chooses a victim that fits his particular, depraved preferences and coaxes the victim to accompany the killer to a lonely spot, where he usually rapes and tortures them and then kills them in a specific way. The killers sometimes moved between Colombia and neighboring countries, particularly Ecuador. The social dislocation brought on by political conflict and drug trafficking has produced a perfect ecosystem for these murderers. A remarkable situation is that often the killers are captured for some reason and then they are released and they continue killing, often for years before being apprehended again. When they are finally captured, the Colombian criminal system usually sentences them to laughably short sentences. Garavito has been condemned for 172 murders, and there may have been as many as 400, but he may be released from jail by 2022, when, if alive, he will be 65. In 2006 when he was interviewed on TV, he looked vigorous and healthy. In Colombia a murderer will receive the same sentence whether he murders 1, 10 or 100 people, because sentences may not be acumulated and we have no (legal) death penalty. Also, they get many benefits for good behavior, for studying and so on. The book also describes several remarkable events, that in the US would probably have been made into movies. Garavito was consulted by the police and he helped them, Hannibal Lecter-like, to identify Manuel Bermúdez, "The Monster of the Cane Plantations", a psycopath who preyed on pre-teen boys and killed 15 of them in cane fields. An expert on serial killers, Jairo Gómez Remolina, was killed by a famous psycopath (Campo Elías Delgado) as he ate in a Bogotá restaurant (Pozzetto). All in all it is an interesting if disheartening read.
