Police in Mexico had been tracking a couple, suspecting them of being tied to the disappearance of three women and a 2-month-old baby. So when cops spotted them pushing a baby carriage Thursday in the Mexico City suburb of Ecatepec, they were hopeful they'd find the infant inside. Instead, they made a grisly find: The baby carriage was filled with body parts, the BBC reports. The couple, referred to as "Juan Carlos N" and "Patricia N," have been arrested, and they're now suspected of being linked to the murders of at least 10 women, though Juan Carlos told a court over the weekend he'd actually killed 20 women, per the Independent. He also says he turned his victims' flesh into pet food, and their bones into fertilizer, El Universal newspaper reports. Prosecutors say Juan Carlos also confessed to sexually assaulting some of the victims before they were killed.
Investigators searched two properties, including the couple's apartment, and found even more body parts stored in a refrigerator and in pails filled with cement. Prosecutors say the couple had been selling body parts from their victims—including 28-year-old Nancy Huitron, who vanished in early September with her infant daughter, Valentina—and neighbors say whenever they saw the pair, they were pushing the baby carriage. Investigators say at least three of the victims, including Huitron, apparently knew the couple, and that Patricia had lured them onto their property by saying she had food and clothing for sale. In the only bright spot, the couple confessed they'd sold Valentina for about $800, and the cops were able to find the baby and return her to her grandmother. The BBC notes that Mexico state, where Ecatepec is located, accounts for the highest number of disappeared women in the country. (Read more Mexico stories.)
