From NBII Studios, this is Truth and Justice, a crowdsourced investigation in real time. I'm Bob Ruff.

What in the hell happened here?

That seems to be the question that the original investigators never bothered to ask about the horrific crime scene on 10th Avenue.

The Gary PD was so quick to close this case with an arrest that they never really bothered to figure out exactly what happened to Anthony Jeffers, Suzanne and Angela Wallace. This case offers a crystal

clear demonstration of the difference between an evidence-driven investigation and a suspect-driven

investigation. The distinction is defined exactly the way it sounds. In a suspect-driven investigation. The distinction is defined exactly the way it sounds.

In a suspect-driven investigation, detectives have already found their guy, and once they

know who did it, then the focus shifts to building a case around that person. They're no longer

trying to figure out what happened. They're trying to create enough probable

cause to warrant an arrest. Here's a good hypothetical example of the difference. Let's say someone

was shot and killed in their home at the end of a cul-de-zac in a middle-class neighborhood.

In an evidence-driven investigation, detectives might check every house on the street to see if they

have ring camera videos of any people or vehicles traveling down the road around the time of the

murder. They would then use that evidence to establish a list of persons of interest that they

would want to speak to. But in that same scenario, a suspect-driven investigation would look very

different.

The detectives again would pull the surveillance videos, but this time they're not looking

to see who was in the area at the time of the murder, because they believe they already

know who did it.

Instead, they're really only interested in whether their guy was around at the time.

On an even more basic level, think

fingerprints. Evidence driven. Run them through APIS to see who they belong to. Suspect driven.
