A 10-year-old girl has been charged with manslaughter in the death of 3-month-old Brooklyn Foss-Greenway who allegedly died as a result of ingested medication and suffocation.

Baby Brooklyn from Clinton, Maine died last July 8 after being left overnight with a babysitter. The sitter called authorities early that day to report that the infant had been unresponsive. After emergency responders arrived on the scene, the baby was not breathing and later died in the hospital.

With some initial suspicion around the baby’s death, the medical examiner’s office finally ruled the death a homicide.

“In this case there was some warning signs that we thought very early on,” Department of Public Safety official Steve McCausland explained. “The medical examiners have confirmed that and obviously the case now has been declared a homicide.”

The baby’s mother, Nicole Greenway revealed that Brooklyn died from ingesting ADHD medication and suffocation, as evident by bruising in her body.

While details surrounding the case have been kept fairly closed, a 10-year-old girl, the daughter of the babysitter has now been charged with the infant’s death and is currently in the custody of the Maine Department of Health and Human Services.

“I feel a little bit of relief that they’re charging her daughter at this point, but the mom really needs to be responsible. She’s the one I left my daughter with,” Greenaway said.

According to WLBZ, the unnamed girl is now the youngest person in Maine to be charged with manslaughter in the last 25 years.

The juvenile suspect will appear in court on October 22.
