A Mexican man who confessed to killing at least 10 women says he would kill again if freed because he hates women and prosecutors are looking into the possibility that he sold the bones of some of his victims.
It was just the latest in a grim list of details emerging from the serial killer case in the poor borough of Ecatepec, just north of Mexico City, after a couple was caught last week carrying dismembered human remains in a baby carriage.
A video posted on social media on Tuesday showed the suspect replying to questions from a doctor at a police station. Authorities have only identified the man as Juan Carlos; in Mexico, a doctor assigned to a police station normally makes the first rough assessment of a suspect's mental and physical condition.
In the video, the suspect sits in a chair close to the doctor, handcuffed. Dressed in a T-shirt and jeans, he shifts between answering calmly and politely, showing self-pity and softly crying.
"Tell the 'bosses' once and for all that if I get out, I am going to continue killing women ... because of the hatred I have for them," he said, with "bosses" referring to police.
He claimed to have been abused by women as a boy and said at one point: "I prefer that my dogs eat the meat of these women, than they keep breathing my oxygen."
The chief prosecutor of Mexico State, where Ecatepec is located, confirmed the authenticity of the video, saying "it is a piece of evidence that was made public" and calling it "a leak by a traitor".
'I was cleaning the world of filth'
Parts of the man's confession may have to be taken with a grain of salt; he previously confessed to killing 20 women, but Gomez said he has been able to provide details — names and description of the victims — in only 10 cases.
Gomez said that authorities are investigating whether the man did in fact sell the bones of some of his victims to practitioners of Santeria, a faith that began in Cuba when African slaves blended Yoruba spiritual beliefs with Roman Catholic traditions. The suspect said that he sold the bones to a man he met at a bus stop.
"We have a line of investigation about one or two people in the area who may have bought them," Gomez said.
A Facebook profile that local media said was run by the suspect was comprised largely of satanic images and ones linked to the Santa Muerte, a female skeletal figure worshipped by a cult in Mexico favoured by petty criminals, drug traffickers and the poor.
Some details of his confession have been backed up by evidence. Investigators have found badly decomposed heaps or bags of human tissue at the three spots where he told police he dumped the remains. The remains were so decomposed that tests are being carried out to determine the age, sex and number of victims.
The man said he was sexually abused at 10 by a female baby sitter, and claimed his mother was unfaithful and tried to knife his father.
The suspect is heard in the video saying he killed women "with all pleasure".
"I was cleaning the world of filth," he said.
