Serial killer couple: A Mexican husband and wife who were arrested while pushing a baby stroller filled with human body parts have confessed to the murder of 20 women. Police said the pair, identified only as Juan Carlos N. and Patricia N., had buckets full of dismembered body parts and cement at the home where they lived with their three children. More human remains were found in a refrigerator. Juan Carlos said he sexually abused some of the women, fed body parts to pets, and sold the 2-month-old baby of one victim. “He actually seemed happy to have done this,” said a prosecutor. News of the murders sparked a protest in Ecatepec, where demonstrators carrying white flowers and candles demanded the government crack down on violence against women.
