What they didn't know yet was that there was still another child in that house on Chickasaw.

Justin Madison, a 12-year-old boy with autism.

This was Jalen's brother, and Jalen was still in that house, too.

Yeah, Nate's got that going.

Justin was terrified and didn't completely understand what was going on.

His sister had fled the scene with her cousin.

Well, more like escaped.

Justin was trapped in an upstairs bedroom and

didn't even know he was injured.

The police were about to wade into a blood-soaked house, but first needed to convince her grandson, Justin, to unlock the door and come outside.

Justin was risking his life letting the officers in because the killer was still there.

In the bathroom, the water was running.

Jalen Plummer was fully clothed, standing under the shower.

The blood from his own knife wounds swirled into the drain.

When asked for his mother's name, he was able to give it to the officer, but he couldn't spell it, saying that she never told him how.

The discovery of the murder weapon was good news and bad news.

Good news that this unlikely and lucky victim found it, but possibly bad news that he cleaned it up.

Justin naturally had a lot of questions about himself, his grandma Diane, and his brother.

who had been led away in handcuffs.

In her bedroom, they found Diane Madison dead of multiple stab wounds, including one that completely severed her carotid artery.
