FAIRFIELD, Maine — A 10-year-old girl has been charged with manslaughter in connection with the death of a 3-month-old baby last month.

John Martin of Skowhegan, the girl’s attorney, was served with a court summons Thursday afternoon, Maine Department of Public Safety spokesman Stephen McCausland said in a press release. The girl is scheduled to appear in Skowhegan District Court on Monday, Oct. 22.

The girl’s name is being withheld by police.

McCausland would not say if the girl was the baby sitter of the infant.

“We’re not discussing her role or getting into any more details on her identity, although we feel she is responsible for the baby’s death,” said McCausland. “Manslaughter was the appropriate charge.”

Three-month-old Brooklyn Foss-Greenaway of Clinton died on July 8 while under the care of a baby sitter in Fairfield. State police declared the death a homicide Wednesday.

“The decision on charging the girl was made after consulting with the attorney general’s office,” said McCausland, who declined to give any additional details about the death. “The state medical examiner’s office continues to work on the case.”

The 10-year-old girl is now in custody of the Maine Department of Health and Human Services, he said.

McCausland said the girl is the youngest person in Maine to be charged with manslaughter in at least 25 years.

“I have not done any research farther out than that,” he said.

The death of any child under age 3 automatically triggers an investigation.

The baby’s parents live in Clinton and had arranged for the child to spend the night at the baby sitter’s Fairfield home, according to The Associated Press.

Emergency officials arrived just six minutes after receiving a call in the early morning hours that the child was unresponsive and not breathing.
