Monday, July 7, 2025
PHILADELPHIA (WPVI) -- Following an Action News Investigation two years ago, there appears to be a level of justice for Sul'Yah Williams.

The 2-year-old girl was killed while in placement with the Philadelphia Department of Human Services.

On Monday, a jury found one of her caregivers, Diamond Joyner, guilty of third-degree murder.

An autopsy report showed Williams died from blunt impact injuries that included contusions to the intestines and bleeding on the brain.

The 26-year-old Joyner will be sentenced in September.
