The lawyer for a woman accused of beating to death a baby under her care on a Montana American Indian reservation says it's unclear if her client intentionally killed the 13-month-old girl.

Attorney Mary Zemyan represents 42-year-old Janelle Red Dog, who appeared in court Friday in connection with Kenzley Olson's Tuesday death on the Fort Peck Indian Reservation.

No charges have yet been filed.

Zemyan says Red Dog admitted to law enforcement that she struck Kenzley, but only an autopsy would determine if that's what caused her death.

She says her client became scared after Kenzley died, and she disposed of the body in a dumpster before reporting to authorities that the girl was missing.

Zemyan says Red Dog had been caring for Kenzley for two weeks at the request of the girl's mother.
