Chicago police say a 9-month-old girl is dead after a relative cut her throat with a power saw.

Officers found the child after being called to a building on the city's West Side on Monday morning.

A police official confirmed media reports that a 52-year-old relative used a circular saw to cut the baby's throat, apparently because she wouldn't stop crying. The official spoke on condition of anonymity because an official autopsy had not been performed.

The official said the woman is in police custody at a hospital with self-inflicted wounds.

Ben Llamas works with the child's father and drove him to the scene. Llamas tells the Chicago Tribune that the father was upset but did not talk about what happened.

Neighbors said several people lived in the home.
