Determining the serial killer with the most kills is difficult due to various factors, including:
- Varying definitions of "serial killer": There is no universally agreed-upon definition of a serial killer, with different agencies and organizations using different criteria.
- Undocumented crimes: Many killings may go unreported or undiscovered, making it impossible to accurately assess the total number of victims.
- Contested attributions: Some killings are disputed, with different theories regarding the perpetrator.
Despite these challenges, Luis Garavito is often cited as the serial killer with the highest confirmed kill count. He is believed to have murdered at least 138 young boys in Colombia between 1992 and 1999.
Other serial killers with high confirmed kill counts include:
- Pedro López: Also known as "The Monster of the Andes," he confessed to killing over 300 young girls in Ecuador, Colombia, and Peru.
- Andrei Chikatilo: Nicknamed the "Rostov Ripper," he was convicted of killing 53 women and children in the Soviet Union.
It's important to remember that these are only confirmed cases, and the true number of victims for many serial killers may be significantly higher.
