Two defendants in this case already admitted to beating Brown to death, and accepted plea deals: Christopher Shakel Williams and D'Angelo Matthews. They were 15 and 16 when they committed the crimes.

Matthews, pictured above, was a Page High student. 

The final defendant made her last appearance in court Tuesday, and was sentenced. She was the youngest to play a part in Brown's murder. 

Ketrellia Harris was only 14 years old at the time of the crime. 

She has spent nearly 4 years in juvenile detention.

Now 18 years old, she pleaded guilty this week to Accessory After the Fact of Murder, according to her public defender Richard Wells. 

The judge sentenced her to 44-65 months in prison. 

Wells says practically speaking, she will likely serve 6 or 7 months of that sentence because of time-served in juvenile detention. 

WFMY News 2 tried to reach out to the victims family for comment, but have not heard back at the time of this article's publication. We did interview Brown's only son right after his brutal murder, and Lonnie had this to say: 

"It's bad how he went out, ya know?" Lonnie Brown stated. "Because he deserved better than that."
