SKOWHEGAN, Maine (AP) -- A 10-year-old girl charged in the death of a Maine infant bit her nails and looked down during her first court appearance.

The youngster entered a plea of "no answer" during her arraignment Monday in District Court in Skowhegan on a juvenile manslaughter charge.

The girl, who's name hasn't been released, is charged in the July 8 death of 3-month-old Brooklyn Foss-Greenway, who was staying overnight in the girl's home in Fairfield in the care of the 10-year-old's mother. Authorities said the girl's mother called police early on July 8 to report that the infant was not breathing. The infant's mother, Nicole Greenway, said Brooklyn was reportedly fussy and slept in a portable crib in the 10-year-old's bedroom that night.

The state hasn't released the cause of death but Brooklyn's mother was told her daughter had ingested medication and was suffocated.

The girl is the youngest to be charged in a Maine homicide in at least 30 years.

The Maine Department of Health and Human Services removed the young suspect from the home and faulted the baby sitter for leaving the infant in the room with the girl. In a letter, an agency case worker said the 10-year-old had a behavior disorder that made her unsuitable for caring for the infant.

The state opted not to try the girl as an adult. If convicted as a juvenile, the maximum penalty is incarceration until age 21.

Maine District Court Chief Judge Charles LaVerdiere issued a special order warning that no recording device of any type was allowed in the courtroom Monday.
