'Serial Baby Killer' Charged With Murdering 3 Infants -- Including Her Own Newborn

In 1985, Nancy Moronez called 911 to report that an 11-week-old girl whom she was babysitting wasn’t breathing. It was clear to firefighters upon their arrival that the infant was dead, and the Milwaukee County Medical Examiner's Office later determined that she died of sudden infant death syndrome (SIDS). Unfortunately, this wasn't the first time SIDS had supposedly struck Moronez's home.


The previous year, Moronez had also called police about a lifeless 6-month-old boy who was in her care. Four years before that, in 1980, Moronez's own 2-week-old son was also found dead, and both cases were also blamed on SIDS. However, now the 60-year-old has finally been arrested for killing these infants, and she was charged with three counts of second-degree murder in Milwaukee County Circuit Court.

The arrest comes after Moronez's daughter approached police in 2015 with concerns that her mom had murdered her brother, according to a criminal complaint. Moronez was arrested on Tuesday, February 20, and has since allegedly confessed to the crimes, saying, "I can't take kids that constantly cry." According to the Washington Post, she has yet to enter a plea.

According to a criminal complaint, Moronez told police that the first murder happened when she killed her 18-day-old baby by holding "him down and [feeling] him wriggle a little under the water." She told investigators that the newborn wouldn't stop crying and so she suffocated him because she felt "helpless." Moronez reportedly then took the lifeless infant out of the tub, "dried him off, diapered him, and dressed him before calling rescue personnel."

Before the second murder, Moronez allegedly told investigators that the 6-month-old had also been crying and she "didn't know where to go." To solve the problem, she reportedly admitted to taking his blanket and holding "real tight against the face," until the baby was smothered to death.

Moronez then reportedly shared details about the 1985 murder, explaining that in this case, she used the baby girl's blanket to pinch her mouth and nose with it until she "turned kind of bluish."

All three of these cases were originally diagnosed as SIDS, and Kent Hymel, a member of the American Academy of Pediatrics (AAP)'s child-abuse committee, recently told ABC News that this condition can be a serious blind spot. According to Mayo Clinic, SIDS is an unexplained death of an otherwise healthy baby that usually occurs while sleeping. This makes it hard "to distinguish at autopsy between SIDS and accidental or deliberate asphyxiation with a soft object," Hymel explained.

According to the Centers for Disease Control and Prevention, around 2,000 infants deaths each year are blamed on SIDS. However, many are starting to worry that SIDS can be covering up cases of foul play, and the AAP released a recommendation for child abuse experts to investigate all new suspected cases of SIDS.

"Interestingly, it doesn't seem like there was any kind of criminal investigation involving Mrs. Moronez until very recently," Matthew Mayer, Moronez's attorney, told the Washington Post. "I'm looking forward to investigating the matter further, and checking into numerous issues, including why it took law enforcement 38 years to point a finger at my client. It shouldn't take 38 years for the cops to solve three alleged homicides."

However, Moronez reportedly told police that she gave birth to her daughter after killing her son and promised God that she would never hurt a crying child again. "I made a promise," Moronez allegedly said. "But I broke it."

Given that her daughter is not only still alive, but is also the one that turned her in, it's unknown how she broke her promise or if there were any other victims.
