According to the criminal complaint, R.J. died from ingesting a "combination of fatal drugs through breast milk" and is being charged with criminal homicide.
Jones' attorney, Louis Busico, said that Jones "absolutely, unequivocally loved that child" and never intended to harm him.
According to an affidavit,
Jones told investigators that about 3 a.m. April 2, she heard R.J. crying.
He had been primarily breastfed, Jones said, but she had recently started using formula because she worried that he wasn't getting enough milk and wasn't sleeping. She was too tired to make a bottle of formula, according to the affidavit, so she decided to nurse him. She then dozed on and off for a few more hours.
Before her husband, Vincent McGovern, left for the day, he made R.J. a bottle and left it with Jones. She remembers feeding R.J., putting him back in his bassinet around 6:30 a.m. and going back to sleep.
In the affidavit, Jones said she woke up about an hour later and panicked when she saw that R.J. was pale and had bloody mucus coming out of his nose. Jones and her mother, who also lived in the house, called 911 and began CPR.
R.J. was taken to a hospital by ambulance and pronounced dead by 8:30 a.m.
According to the Bucks County Coroner's Office, the autopsy revealed traces of methadone, amphetamine and methamphetamine were found in the infant's blood and contributed to his death.
The affidavit further noted that the examiner who performed the autopsy said "R.J. ingested the combination of fatal drugs through breast milk."
According to the affidavit, Jones told the investigators that she had been prescribed methadone since pregnancy to help manage her addiction to opioid painkillers, but there is no mention of other drugs.
Investigators say they tested the bottle last used to feed R.J., as well as the can of formula, and found no traces of illicit drugs.
Since her arrest, Busico said, his client is "completely in a state of depression." He added that the charges and arrest kicked Jones when she was already down, dealing with the death of her child.
When asked about amphetamine or methamphetamine drug use by Jones, Busico would not comment.
At Jones' preliminary hearing on Wednesday, Deputy District Attorney Kristin M. McElroy argued that the child died because Jones had taken methamphetamine and amphetamine, "which had no business being inside that baby," according to a press release
from the Bucks County District Attorney's Office,
"We are not alleging that this was an intentional killing of this baby," McElroy said, "but it certainly was reckless to know these drugs were in your body and continue to breast feed."
The criminal homicide charge was upheld and Jones now awaits a formal arraignment on September 28.
Busico said Wednesday he was not surprised by the decision.
"The judge's ruling today is no surprise given the low burden on the government," he said. "Samantha is not criminally responsible for her son's death -- this is a fact pattern in search of a crime."
Through her attorney, Jones declined to speak with CNN.
Drug epidemic and pregnant women
There have been just a handful of cases in which mothers have been criminally charged in cases related to drugs and breastfeeding.
, a California woman pleaded guilty to the involuntary manslaughter of her 3-month-old son by nursing him while on methamphetamine. In 2012,
Maggie Jean Wortman, also of California, was sentenced to six years in prison for voluntary manslaughter of her 6-week-old due to methamphetamine in her breast milk. In 2014
, a Washington woman was charged with endangerment with a controlled substance by breastfeeding her 2-year-old daughter while using methamphetamine, cocaine and marijuana.
In the medical literature, the cases of fatal infant poisonings by breastfeeding are also few and far between. One of the few examples was a letter in the medical journal JAMA regarding a 1994
case; it involved a 2-month-old
in California who was found dead eight hours after breastfeeding. Although prosecutors were able to charge the mother with child endangerment, doctors who wrote the letter questioned the role low levels of meth concentration played in the infant's death.
Dr. Poj Lysouvakon,
pediatric director of the Mother-Baby Unit at University of Chicago Medicine, said such cases are controversial.
"There is no definitive proof that these substances were the primary [or] sole cause of death for these babies. There is not a huge body of medical literature that can definitely prove or disprove that the small amounts of these substances found in breast milk are enough to be the cause of death in these babies," he said.
But as a drug overdose epidemic continues to ravage America, prosecutors have become more aggressive in charging drug overdose cases as homicides.
The US Centers for Disease Control and Prevention estimates that over 72,000 people
died of drug overdoses last year, many of them from opioid-related overdoses. The number of opioid overdose deaths is now more than five times
high as in 1999.
The crisis extends to pregnant women, as well. The CDC's latest numbers say the rate of women delivering babies while abusing opioids has more than quadrupled between 1999 and 2014.
It's a public health problem that doctors say needs medical attention, for the benefit of both the user and the child -- and that can extend to breastfeeding.
