MOUNT VERNON, Mo. (AP) — A southwest Missouri woman was sentenced to five years in prison in the death of her 4-year-old son.

The sentencing on Tuesday of Jade Murray of Aurora came after she pleaded guilty last week to second-degree domestic assault. She had originally been charged with second-degree murder in the December 2014 death of Skylar Bradley.

The Joplin Globe reports Murray was accused of hitting her son hard enough to knock him off his bed, causing his back to hit his brother’s bed. The boy died later at a Springfield hospital.

An autopsy determined he had a ruptured spleen and also suffered bruises across his body.
