According to a police affidavit, the caregiver for Lillie Jones, 78, arrived at her home to find the woman “sitting in the dark, crying and bleeding from the head” around 4 p.m. Tuesday.

Jones, who is in a wheelchair, requires assistance from home caregivers.

However, earlier that day, when Jones went into her granddaughter’s bedroom to ask for help, it took a violent turn.

Investigators said Jones woke up her granddaughter, Pamela Jones, which angered her. An “argument ensued.”

At that point, police said Pamela Jones grabbed a broom and struck her in the head with it with "enough force to cause the broom to break."

When police arrived at the scene, officers found the broken broom with blood on it in Jones’ room.

The victim was treated for a head contusion and laceration, which was still bleeding when emergency responders arrived.

Pamela Jones was arrested and charged with aggravated assault, to wit, domestic violence. Police said she is out on $25,000 bond.
