ALTAMONTE SPRINGS, Fla. (AP) — A teen in Florida is facing a manslaughter charge after police say she killed her 3-year-old sister by putting a pillow over her head after their mother told the girl to quiet the toddler.

The 16-year-old girl was arrested Friday in an Orlando suburb.

A police report says the 3-year-old girl was being loud so their mother asked her older daughter to keep her younger sister quiet in a hotel suite’s living room while she was on the phone for work in the bedroom.

Police say the teenager put a pillow over her sister’s head to quiet her and when the woman returned to the room, the toddler was unresponsive.
