Mario Alberto Sulú Canché

Mario Alberto Sulú Canché (1979 – August 29, 2008), known as The Young Girls Killer (Spanish: El Matachavitas), was a Mexican serial killer who killed three women in rural Mérida, Yucatán between 2007 and 2008. He was sentenced to 40 years imprisonment for these crimes, and later hanged himself in prison.

Background A native of Mérida, Yucatán, Mario Sulú was a plumber by trade. He was born into a dysfunctional lower-middle-class family and as an adult struggled to keep stable employment, often resorting to stealing. As a teen, Sulú committed various criminal offenses, including theft, sexual harassment, armed robbery and rape. According to some psychiatrists, he might have suffered from antisocial personality disorder.

Murders Sulú would approach his victims under the pretext of offering them employment at a supermarket, tricking them to get into his car. He then took them to secluded areas, where he began to make sexual advances towards them. When his advances were rejected, Sulú became violent and raped them. Eventually, in an effort to not get caught, he started killing his victims, whose bodies he either dumped in the sea or buried on the roads in isolated areas. He would also take their personal belongings, which he later sold.

His first victim was 15-year-old high school student at COBAY Chenkú, Alma Lucely Canul Ciau, whom he approached as she was leaving school in June 2007. He had also supposedly left his DNA on all of the bodies, but when it came to the very first murder, the salt water from the sea and the advanced state of decomposition rendered it unreliable. Regardless of this, Sulú would be arrested on August 4, 2008, after several witnesses positively identified him as the last person they had seen Alma Canul be with.
